The hour of our birth had been carefully forecast, a winter’s day Cesarean timed to coincide with Dr. Feng’s lunch break. The doctor pulled me out first, indignant and squalling, like a hotel guest roused and tossed before checkout. Lulu came next, and was so perfectly quiet that at first they thought she wasn’t breathing at all. Then they thwacked her on the back and her cries joined mine and they laid us side by side, boy and girl, two underwater creatures suddenly forced to fill our lungs with cold dry air.

Dr. Feng had operated on our mother as a favor to our uncle, his old classmate. Otherwise we would have been born in the hospital down the street, where a woman had bled to death after a botched Cesarean the previous year. The family had been in the waiting room for hours, and at last the father-to-be pounded on the doors of the operating room. When no one responded, the family pushed them open to find the lifeless woman on the table, blood pooling on the ground. She was alone: the staff had stripped the medical certificates that bore their names from the wall and fled as soon as the surgery went wrong.

From the start we were lucky, not least because we had each other. As twins we’d been spared the reach of the government’s family-planning policies. For the first few weeks of our life, our skulls had matching indentations from where they’d been pressed against each other in the womb, like two interlocking puzzle pieces. Later in life, when we were apart, I used to touch my hand to the back of my skull when I thought of her, as if seeking a phantom limb.

We weren’t in any way an extraordinary family. My mother worked as a warehouse clerk, my father as a government sanitation planner. When he was forty-seven, his division chief—a fanciful man who once dreamed of being an artist—decided to build a public toilet in the shape of a European clock tower. He’d been to Europe and had been impressed by the cleanliness of the toilets and the loveliness of the architecture and wanted to combine the two. Like most artists, the division chief had a fragile ego, and shortly after my father balked at the project’s expense he was fired. It was the sole act of independence he’d committed in his life, and it cost him his career.

From the time Lulu was ten, my parents worshipped at her altar. Her precocity was evident early on; it was like a flag being waved energetically from a mountaintop. Neither of our parents had much education, and it stunned them to find themselves in possession of such a daughter.

When we were small, we played devotedly together. Lulu was a great inventor of games, which often incorporated whatever she’d read most recently: one day we were stinkbugs looking for the right leaf on which to lay our eggs; another we were herdsmen fleeing Mongolian invaders. She was braver than me; once, she even snuck into the apartment of the elderly woman who lived opposite us and had left her door ajar while retrieving the mail downstairs.

“It’s full of newspapers, stacked as high as your head,” Lulu said excitedly, eyes glowing as she dashed back to our apartment. “There’s a giant orange cross-stitch on the couch, with a peony and six fishes.”

As a child she was always reading: even at meals she would sit and scan the back of the juice box. She must have read it a million times, aspartame and xanthan gum and red No. 9. It wasn’t a conscious thing—she just seemed to feel uncomfortable when her eyes weren’t fastened to a page. She had a mania for lists, too. By eleven she’d memorized every bone in the human body, and she used to recite their names to me at night in an eerie voice as I held a pillow over my head: sternum, tibia, floating rib.

In high school, I rebelled against her brilliance by playing video games, lots of them, spending hours whipping a gun back and forth across dusty landscapes empty of people, except for those who wanted to kill you. Usually there were six or seven of us at my friend Xingjian’s apartment, and we would take turns and cheer one another on. We were an army, invincible, or if we weren’t invincible we could hit Replay at any time, which was pretty close to the same thing.

Lulu, meanwhile, was a model among model students. She studied so intensely that it left her physically bowed and exhausted, like an athlete running a daily marathon, and at night she dropped off to sleep without a word. My mother fed her stewed mushrooms that looked like tiny brains when their stems fell off—they would be good for Lulu’s studies, she said. She gave me some as well, though by then it was plain that any hopes for academic glory resided with her daughter, not her son, the constructive effects of mushrooms be damned.

When we sat for the college-entrance exam, it surprised no one that Lulu scored high enough to earn a place at a university in the nation’s capital, a bus and a train and a plane ride away. My mother wept with what she said was happiness. “A scholar,” she kept saying. “A scholar.” She and my father, she liked to remind us, hadn’t studied long before going to work in the factories.

“We are so proud,” my father told Lulu. There was an intensity to his expression that unnerved me. One of our schoolbooks had a black-and-white illustration of a long-ago eunuch serving a feast, staring hungrily at the food on the emperor’s table, and there was something of that look on my father’s face.

The night Lulu left was overcast, the twilight that preceded it a peculiar mixture of orange and ochre. Earlier that day, my father had given her a gift: her very own laptop. It was thick with promise, like a fat slice of cake, sheathed in blue plastic. It wasn’t like the old computer that we all shared, which stuttered and stalled, its keys sticky with grease and crumbs and bits of hair. This one had keys that yielded obediently when you touched them. I’d stared at it enviously, too filled with longing for words. “Don’t worry, you’ll get one, too, when you leave, the exact same,” my father said.

At the airport, our parents assumed expressions appropriate for refugees being abandoned at a border. “Lulu, be good,” my father said. I stood there awkwardly, a little resentfully. Lulu turned and flashed a peace sign as she went through security, and we watched her pink hoodie and striped zebra baseball hat retreat into the crowd until she was gone.

Ideparted for college a week later, with considerably less fanfare. The school was just an hour’s drive away and had an empty feel to it, as though it had been erected with much ambition years ago and then forgotten. In the winter the dorms were freezing, as if their concrete walls held in all the damp, cold air and kept it close to your skin.

The best thing about college, I decided, was that the dorms were wired for the Internet. There were five other boys in our room on the second floor, sharing rickety metal bunk beds draped with mosquito nets, which afforded both a thin sense of privacy and protection from bites in the summer. At night, when we sat in front of our computers, you could hear the same tinny chirping of chat alerts all around you, emanating from the floorboards, the ceilings, and the walls, as though hordes of invisible, electronic crickets had stormed the building.

I wasn’t old enough to miss Lulu. Anyway, I could see her chat statuses whenever I logged in on my new laptop, smooth and shiny and housed in a blue plastic sleeve just like my sister’s. Studying, they might say. Going to class. At some point they got more fanciful. Floating down the green river, one read. Digging into a stone with no edges. Sometimes, bored while waiting for my gamer teammates to log on, I looked them up. A few belonged to old poets, but the rest, I suspected, she was inventing herself.

I died repeatedly that semester, but amassed several hundred gold coins and was made first a warlock, then a mage. The other boys in my dorm were addicts, too, and we played fiercely into the evening, cussing, headphones on, until midnight, when the power was cut. Classes were a negligible affair: what mattered was your grade on the final exams, and those could readily be crammed for by memorizing ten or fifteen pages of mimeographed notes sold by upperclassmen. Honestly, I had no idea who actually went to class: I pictured teachers sitting with their laptops in front of empty rooms, one eye on the clock, maybe playing video games of their own, maybe taking a nap.

In our second year of school, I searched idly for one of Lulu’s statuses and found just one result: a public microblog with a profile photo featuring a yawning yellow cat. There were several dozen posts, mostly the same kinds of snippets of poetry that Lulu had been posting to her statuses, and by the time I finished scrolling through them I was sure the account was hers. For the bio she’d written qiushi, a reference to the old Communist maxim “to seek truth from facts,” but the name of her account was qiu zhushi, “to seek carbohydrates,” which made me laugh. You wouldn’t have suspected it to look at her, but Lulu was a glutton—she could eat reams of noodles or fried crullers without missing a beat.

One day in the dorm, I answered a knock at our door to find a classmate grinning at me. “Your sister’s here,” he said. I gaped and went downstairs. There she was, wearing an old-fashioned padded blue coat, the kind common in the fifties. Lulu had her hair in two braids, carried a knapsack slung over one shoulder, and was smiling. She’d joined the college debate club, she said, and they were travelling for a competition. “Big Brother,” she said—it was an old joke of hers, since I was born only a minute or so before her—“want to buy me dinner?”

I suggested the cafeteria. She said she had something nicer in mind, and took me by the arm to a coffee shop near the campus entrance. The place called itself Pretty O.J.; its sign advertised Italian noodles. I’d walked by dozens of times and never gone in. Inside, the tables were topped with glass and the seats were an uncomfortable white wicker that crackled when you shifted and there were white vases to match, filled with plastic flowers. Lulu took hold of the menu and confidently ordered a pizza and tomato pasta for us as though she’d done it many times before. “With coffee, please,” she added, “and bring us some bread.”

I stared at her. “You look happy,” I said. She was. She was debating at a college an hour’s drive south, she said, and had taken a bus to come and see me. I asked her if our parents knew, if she was planning to see them as well.

“No,” she said, smiling. “We fly back tomorrow night, but I wanted to see you.”

Beside her I felt very young in my rubber slippers and T-shirt and shorts. She asked me about my classes and my friends. I told her that I was watching a lot of television on my laptop and playing even more video games. Lately, I’d been playing with a team of Russian teen-agers who were pretty good. We didn’t speak the same language, so we communicated in a kind of pidgin English: don’t worry guys I got phantom princess no no no, you NOOB, dafuq.

“I know you think it’s a waste of time,” I said.

“A lot of kids play it at my school, too,” she said, not contradicting me.

“It’s a profession now, you know,” I said. “They have competitions, you can win big prize money.”

It embarrasses me now to realize that, up until that point, we’d spent the whole evening talking about my life. I don’t think I asked her anything about her own, and it was only at the end of our dinner that she volunteered a few facts. She was pregnant, she said, two months along, and very much in love with the baby’s father.

I choked on the coffee. Lulu waited for me to compose myself, and then she told me the rest of the story. The father, an upperclassman studying accounting, was from a poor county in the northeast. No, they weren’t keeping the baby, though she and Zhangwei would likely get pregnant again in a few years, “after we’re married,” Lulu said, with a calm matter-of-factness that astounded me. Someday, the two of them hoped to travel abroad.

She told me more about him, choosing her words carefully. “He’s not like other people,” she said at last. “He’s very noble.” It was a strange word, an old-fashioned word. I just stared at her.

“You’re sure about all this, Lulu?”

“I’m sure.”

I envied her for a moment, sitting there looking so certain. When had I ever been sure of anything? For Lulu, everything had always come so easily and confidently: homework, answers on tests, college, and now, it seemed, love as well.

When the bill arrived, I didn’t have enough money with me, so she paid. “Thanks, Big Brother,” she said when we left, and at first I thought she was being sarcastic, but she looked glad when she said it. “I haven’t told anyone else,” she confessed as we walked out into the blue twilight, the boxy concrete façades of the campus around us. “I knew I could trust you.”

This was the first time it had occurred to me that I was trustworthy, and it was a relief to hear that I had been evaluated and not found wanting. “Of course,” I said.

In the following months, I checked her account more often. I got flashes of insight into her life that way: photos of the yellow shocks of forsythia that blossomed in the spring, more odd bits of poetry. I pictured her tapping away at her identical, blue-sheathed laptop across the country, clicking Send.

That fall, she started posting daily about someone named Xu Lei. It was a name that even I’d heard by then, enough people were talking about him. He was a college student who’d been picked up by the police outside a karaoke joint, and been beaten, and died while in custody. Photos of him before his death had circulated online: skinny legs in shorts, glasses, a purple T-shirt that read “Let’s Go.” He and his friends had been standing outside after singing karaoke, a little drunk, and when the police told them to move along Xu Lei got caustic and the officers took offense. His friends had filmed them beating him and then loading him into a police van. As quickly as censors took down the footage, it was uploaded again.

Mostly, Lulu was just sharing other people’s messages, adding her own hashtag #justiceforXuLei or an indignant frowning face. At some point, she added her own commentary: “This country, these police, are simply too dark.”

When the police autopsy came out, it found that Xu Lei had died of a heart attack. The conclusion was promptly met with scorn—he was only eighteen. The coroner’s report said that, prior to his death, he’d been working hard and not sleeping well. “It was a young person’s heart attack,” it concluded, a phrase that quickly trended online until censors snuffed it out. Lulu was not impressed. “I have studied hard all my life and I don’t sleep well,” she wrote. “Will I, too, be made to have a heart attack?”

After that, Lulu’s account became more active. At first she was just reposting news from other accounts: the tainted-formula scandal that killed three babies, the college-admissions administrator found to be taking cash bribes—the kinds of things we all knew and groused about.

A few months after that, though, she began to flood her account with images and videos that were genuinely surprising. I had no idea where she was getting them. They were of scattered street protests from around the country, some just stills, others clips of perhaps a few seconds, rarely more than a minute long. Hubei, Luzhou city, Tianbei county, Mengshan village: 10 villagers protest outside government offices over death of local woman, one might say. Or: Shandong, Caiyang city, Taining county, Huaqi village: 500 workers strike for three days, protesting over unpaid wages.

There were dozens of these posts, and they usually looked similar: police in pale-blue shirts, lots of shouting, crowds massing in the streets, occasionally someone on the ground being beaten. In one video, several men were attempting to tip over a police van. In another, a group of villagers were shouting as something that looked horribly like a human figure smoldered on the ground.

“We really need to get laundry in our building.”

They were like dispatches from a country I had never seen, and they disturbed and confused me.

After seeing the video of the self-immolation, I messaged her. Are you O.K.? I asked. The reply came a few hours later: Hi Big Brother! I’m doing fine.

Are you in Beijing?

Of course I’m in Beijing.

I stared at the blinking cursor. I’d never told her that I knew her identity online, and I worried that if I said something she’d see me as somehow untrustworthy, as though I’d been spying on her.

Beijing must be very cold now, I wrote at last. Make sure you wear warm clothes.

That February, we both went home to see our parents and to celebrate the Spring Festival. I took charge of the dumplings, chopping the fennel and leeks, cracking an egg and swirling it about with gusto. I was happy. The week before, our team had entered a local competition and had won a month’s supply of instant noodles and certain bragging rights. Replayreplay: my hands knew the commands so instinctively that sometimes I’d wake in the dark with fingers twitching.

Lulu, though, seemed only partly present: often you had to call her name twice to get a response. Sometimes I’d get up to use the bathroom in the middle of the night and see a glow in the living room, which meant she was awake and online.

One night we gathered around the television to watch the Spring Festival gala. It was an annual tradition put on by the state broadcaster: cheesy skits, patriotic odes, terrible slapstick—the whole country watched. I excused myself and logged on to check Lulu’s account. The most recent post was from that evening, just before we sat down to dinner. It was a line of text in quotation marks: “If you want to understand your own country, then you’ve already stepped on the path to criminality,” it read. And then: “Happy Spring Festival, comrades!”

A shiver ran through me. I logged out and walked back into the living room. Our parents sat on the couch, with Lulu on a stool beside them, their faces pallid in the television’s flickering light as I joined them, stealing glances at this strange person, my twin sister.

The next day, the two of us went out to buy some ingredients for my mother: flour, fermented bean paste, ground pork. It felt strange to walk the half mile to the supermarket together, the first time we’d been alone since she visited me at college.

On the way, we passed a park where we used to play as children, and we could hear the sound of children there now. It was sunny, and the warmth lulled my skin.

“Where did that quote come from?” I said. “The one from last night.”

She kept walking. “What do you mean?”

“I’ve been reading your account.”

“I don’t know what you’re talking about.”

“Come on, Lulu.” I stopped walking. “I’m worried about you.”

She stopped a few feet ahead of me and stood there, not looking at me, arms crossed. “How did you know?”

I explained about the poetry. “Do other people know it’s you?”

She shrugged. “A professor. Some other students.” When I pressed her, she said reluctantly that a classmate had reported her to the department head, and that one of her professors had taken her aside and gently warned her that she should stop her activities online, lest it “influence” her future.

“They’re right, you know,” I said. “Don’t you worry about how this might affect you?” One of the videos she’d posted, I remembered, showed a woman kneeling on the ground and wailing, “The government are traitors! The government doesn’t serve the people!”

Lulu just stood there, staring at the little shopping complex opposite us as if she were trying to memorize it. There was a bilious-orange fast-food restaurant, three test-prep centers, and two real-estate agents’ offices.

“Or our parents?” I said. They’d both retired by now, but each had a modest pension that I imagined could be taken away, and, anyway, the ruining of Lulu’s prospects would be the greatest loss of all. When I thought of having to support them on my own in their old age, my stomach creaked unhappily.

She nodded. “Of course,” she said, finally. “I’m not stupid.”

“So you’ll stop, then?”

She looked at me for a moment, a little dreamily. “Did you know that in the Song dynasty it was illegal to throw away any pieces of paper with writing on them?” she said. “People had to go to certain temples with sacred fires set up where they could burn them instead. That’s how much they revered the written word.”

I wanted to shake her, but I didn’t. “I don’t see how that’s relevant.”

She started walking again.

“Where are you getting all this stuff?” I asked. She unbent slightly and explained that she had downloaded a tool that unblocked overseas Web sites. “It’s not hard,” she said. “But things get deleted quickly, so I have to keep reposting them.”

“I had no idea these kinds of things went on,” she added, soberly. “We were lucky.”

“We weren’t rich.”

“Dad worked for the government. We were comfortable.”

Of course we were, I told her, but so were lots of people, and it didn’t mean that she had to expose herself to trouble.

“It’s better than just playing video games all day,” she shot back, suddenly angry with me. “What’s the point of that?”

I stuck my hands in my pockets and shrugged, taking a few extra breaths to calm myself. It was strange to see Lulu angry; she was usually so even-keeled. “Fair enough,” I said. We kept walking, not looking at each other. Inside the supermarket we parted, as though with relief.

Back on campus, spring brought translucent white buds to the trees, like the tiny cores of onions. Lulu had stopped posting, I was pleased to see. I began working part time at a restaurant downtown that served large, expensive banquets, helping to prepare plates of cold chopped meats and glassy collagen and frilly slices of cucumber dolled up to look like miniature peacocks. There was a rhythm and a repetition to the work that I liked, a sense of contentment in washing up at the night’s end and putting things back where they belonged.

One day in May, just before graduation, I checked back in on my sister’s account. Lulu had stopped updating her chat status; for several weeks, it had read simply “out,” and I’d grown worried.

It was as it had been before: she’d gone back to posting frenetically, as though she’d lost control—in one day alone she had posted forty-three times. There were the same postcards of protests around the country, the videos and photographs she’d been sharing before, and a lot of simple text posts, too, one after another. 3:34am: if this country were a vegetable it would be a rotten, bitter melon. 3:36am: I am the daughter of a government sanitation worker. I know the smell of s---. 3:37am: I’m sorry, friends, just a little tired today after so many posts. There are many beautiful things, too, in this life. And then she’d shared a series of pictures of small goats leaping in the air, tiny hoofs aloft against green grass. 3:41am: O.K., I am sufficiently soothed to go to sleep. Good night comrades, until tomorrow.

The posts went on and on—thousands of them had accumulated in the time since I’d stopped checking. I scrolled through them with a mounting sense of horror, and then paged back up and felt my stomach flip: somehow she’d amassed eight hundred thousand followers.

I messaged her frantically, fingers scrabbling at the keys. Goats?

A few hours later, she answered me. Did you like them?

They’re O.K.

I’m sorry, Big Brother. I couldn’t stop.

I sat and watched the cursor blink, like a slow pulse.

A lot of people are paying attention to you. I couldn’t tell if I should be proud of her, worried for her, or angry with her. I supposed I was all three.

Yes, they are. Another long silence. Don’t be upset, Big Brother. I just felt this was something I had to do. Don’t you agree?

I’m working now, I wrote her, hoping she could sense my anger. Running late, got to go.

After she graduated, Lulu moved in with her boyfriend, Zhangwei, in Beijing. She started her own anonymous Web site, a constant stream of news about protests and human-rights abuses around the country. There was the story of a woman, beaten to death by police, whose daughter had paid to keep her body frozen in a morgue for six years, unwilling to inter the evidence. There was the story of the village where officials had torn down an elderly grandmother’s home in the middle of the night to make way for a shopping mall; she’d been given no warning and had died in her bed as the roof collapsed around her. Each post carried its own mordant title: “The Mother Popsicle,” “The Frustrated Sleeper.”

They came for her one night, to the third-floor apartment that she and Zhangwei were renting. They burst in through the door without warning and informed her, politely, that she should go with them. “The landlord must have given them the key,” she told me later, stunned. It was that particular detail, oddly, that seemed to haunt her.

It was midnight when Lulu called me from the police van to say that she was being taken away. “Tell our parents,” she said. “Please. I’m sorry.” Her voice broke, and I barely recognized her. She sounded like a child in a blizzard who’d lost her scarf. It was easier to think of that than to think of the alternative: Lulu, cuffed into a van and taken away by four men who sneered at her for being unmarried and living with her boyfriend, for trying to stir up trouble, for spreading rumors—a crime punishable by seven years’ imprisonment.

When they began interrogating her, it was worse. “Did you go to any of these places?” they kept asking. “Did you confirm any of these things yourself before spreading these rumors online?”

No, Lulu said. No.

“So you didn’t know if they were true, then.”

Later, they laid her on the ground and kicked and beat her. They didn’t fracture any bones, but I pictured her bones anyway, each individually absorbing every blow. Lulu would have known them all by heart: sternum, tibia, floating rib.

I called my mother, who on receiving the news, still half-asleep, went blank. “You must be mistaken,” she told me sharply. “Let me call Lulu to straighten things out.” It was an old reflex of hers, this instinct to turn to her daughter. “You can call, she won’t answer,” I said, but she’d already hung up. When I called back, my father took in the news helplessly, as though he’d been expecting it. I tried to explain the kinds of things she’d been writing, but he cut me off. “Lulu is my daughter. I can imagine,” he said. There was a particular heaviness in his voice that surprised me, and it made me think that maybe he’d known her better than the rest of us.

Lulu was freed after six days, and went back to her apartment to convalesce. We flew to Beijing the next day to see her. It was the first time I had been in her apartment, whose living-room wall bore a giant decal from the previous tenant, featuring silver and pink trees and a striped pink kitten. You are my happy surprise friends are better in autumn, it read. Lulu’s skin looked yellow and darkly bruised, and there was a dart of something red in her right eye that peeked out when she looked in certain directions.

“I’m all right,” she said. She seemed acutely embarrassed to see us. They’d only wanted her to stop what she was doing, she said. She’d been a good student, one of the best in her class—she didn’t have to ruin it all. It was a misunderstanding, she told us. They’d let her go, after all.

It seemed that she wanted us to go, too. We stayed for a week, our mother fussing in their tiny kitchen, preparing large meals of things sliced and intricately diced and cooked over a high flame. “I’m O.K.,” Lulu said, until we stopped asking.

Back at home, Lulu started chatting me late at night, at odd hours. I was usually awake anyway: after graduating, I’d moved back home to work in the kitchen of a local hotel. I spent my days chopping and rinsing, bleary-eyed, and my nights with teammates, locked in online combat. There was something that intensified in her messages during those months. She wanted to know how our parents were, if it was raining, if I’d eaten yet. She wondered if she could sue the police who’d beaten her; she’d been having stomach pains ever since. She wanted to know if I remembered the story of the mother who had died in the hospital down the street from us before we were born. She wondered if there was any way to locate the dead mother’s child today—it would be about our age by now.

After that, the posts on her site started up again, thick and fast. I watched with a sinking heart, trying to distract her. When are you and Zhangwei getting married? I tried. Didn’t you want to have a baby? Soon, she said. Maybe.

When the police came and took her away again, she was prepared; she got up quietly from the couch and went with them without a word, leaving her keys behind. This time, when they allowed her access to a phone, she called a lawyer, not me. The police raided the apartment, taking her computer, the blue-sleeved laptop my parents had given her. They also left behind a notice saying that she was formally being arrested and charged.

At the trial, Lulu wore an orange jumpsuit and her hair had been shorn so short that she was barely recognizable. She stared straight ahead at the prosecutors, never once looking out at the audience. We’d flown out for the occasion—we hadn’t seen her for six months. She was given a sentence of three years, then jerked away through a door at the opposite end of the courtroom, and that was all.

On the plane, my mother wept all the way home. “What more did she want?” she kept saying.

To her left, my father hushed her. “There’s nothing we can do now,” he said. The thought, strangely, appeared to console him.

Back at home no one seemed to know that anything had happened to my sister, and no one asked, either. It was as if a great white blanket of snow had descended, softly muffling everything in its path.

Time passed, and eventually I was made a sous-chef at the hotel, with a modest raise and a new, slightly taller paper hat. When I felt restless or agitated, which was often, I’d log on and join my teammates online.

One night I brought my girlfriend home for the first time. I’d met her the month before on the lowest basement floor of a warrened-out block devoted to the sale of electronics: a fluorescent-lit maze of close-set tiny booths selling secondhand phones, cases, speakers, and power banks. Her name was Mao Xin, and she was one of the few girls working behind the counters there. She could tell you the difference between 100 Wh and 161 Wh, could quote the price per gigabyte of different models.

As it turned out, she’d grown up riding the same bus route as I had, and in a city as big as ours that was enough to feel like fate. We liked to imagine that we had seen each other on the bus as children, stiffly bundled in the winter or swinging our legs impatiently in the summer, had maybe even clung to the same pole.

Over dinner that night, as we sat and slurped potatoes stewed with ginger and pork, my mother quizzed Mao Xin. I could see that she wanted to like her, had observed the way she’d helped chop the garlic and cut the yellowing tips off the chives. Mao Xin exuded a kind of benevolent competence that soothed everyone, even my mother, who had grown jittery since Lulu’s trial, prone to repeat herself, easily annoyed.

As we talked, I could see Mao Xin’s curious eyes flicking around, eventually landing on a photo of Lulu atop a bookshelf across the room, high enough that you needed to squint to really see it. “Who’s that?”

“It’s his sister,” my father said. The photo had been taken the day she had won our district’s top score for math in the college-entrance exam. In it she was grinning maniacally at my father behind the camera, a little out of focus.

“I didn’t know you had a sister,” she said to me. “She looks like you.”

“They’re twins,” my father said.

“Where is she?”

“She’s in the northeast, preparing to get her Ph.D.,” my mother said.

Later, when I walked Mao Xin outside and explained what had really happened, her face fell. “Oh,” she said. “I’m so sorry.” When she was growing up, she said, there was a man who used to station himself outside the government offices down the street from her home, with torn fatigues and sneakers so worn they flopped open like petals around his ankles. He’d tell anyone who would listen about how the Army owed him seven years of back pay. He’d been there every day through her childhood, she said, until one day he disappeared for good.

“It sounds like he was crazy,” I said.

“I think so,” she said. “Maybe not at first, though.”

“You must have been scared of him.”

“More just sorry for him,” she said.

We planned our wedding for a few days after Lulu was to be released from prison, a boisterous dinner in the nicest hall of the hotel where I worked. I’d been made a full chef there that month, which felt like a sort of wedding gift. We served big platters of cold, jellied meats and swans made of mashed-up radish, with carrot beaks and black sesame eyes. It should have been a happy occasion, and I guess it was, but whenever I looked at Lulu, sitting across from me with a distant look in her eyes, my heart caught in my throat.

As the banquet wound down, my father, unnatural in a rented tuxedo, began coughing violently. When he didn’t stop, Zhangwei signalled to one of the waiters for water.

“Drink up,” Lulu said. He drained the glass, almost angrily, it seemed. The coughs sputtered, subsided. “You’re O.K.?” she said.

He had been drinking, his face was flushed, and his eyes focussed suddenly on her, as though surprised that she was there. “Do you think what you’ve done is meaningful?” he said.

“Let’s not talk about it.”

“You didn’t even know these people,” he said. “Whatever their problems might have been, they had no relation to you.”

Lulu looked down at her plate, seeming not to hear. She’d grown adept at that while in prison, or maybe she’d always had that skill: how to sort the world into clear categories, what she thought was worth paying attention to and what wasn’t. I was in the latter category now. She’d nod at me occasionally and respond when spoken to, but that was all. I tried not to let it upset me.

His face was getting redder—none of us had ever seen him like that before. “Dad, let’s just leave it,” I said. Guests at nearby tables had stopped their conversations, craning to hear. “It’s no use.”

“You are our daughter,” he said fiercely, ignoring me. “Everything we could, we did for you. You were all our worries, all our hopes.”

He was coughing again, small mangled noises sticking in his throat. Lulu’s expression softened. “Dad, drink more water. It sounds like you’re really sick.”

He ignored her, setting the glass down in the same ring of condensation. He was suddenly an old man, or maybe I’d only just noticed. “Do you think I had your chances in life?” he said. “Do you know what I could have done if I had them?”

It was hard to believe that the two of them were fighting; it was something I hadn’t seen before. Our mother and I looked at each other, then looked away.

“I’m sorry,” Lulu said quietly.

“You want to help people, Lulu, but don’t deceive yourself,” he said. “All you’ve done is hurt yourself, hurt your family.”

My mother laid a hand on his and stilled him with a look. Zhangwei stood up, as though to end the discussion. It made you aware of what a tall, fine-looking man he was, stiff black hair that stood up in a dense thatch, thin lenses highlighting his watchful brown eyes. “I think Lulu had better get some rest now,” he said to my parents. There was nothing impolite about his tone, but there was a finality to it that reminded us all of his solidity, his determination to protect my sister, and I liked him the better for it.

“Don’t worry,” he told me as he ushered her outside, away from the noise and the lights of the wedding party. “I’ll take care of her.”

She hadn’t been treated badly in prison, she’d said when we were all first gathered again in our parents’ living room. There had been a female guard she suspected of having a crush on her, who used to smuggle her packets of instant noodles and an occasional stick of gum. During the day they’d worked on a manufacturing line, assembling Christmas lights. At night they’d watched the evening news and whatever sports match was being televised. But she’d missed the sunlight, she said. She’d missed Zhangwei, missed us.

“Thank you for your letters,” she said to me, and I looked at the floor, away from our parents. “It was no problem,” I muttered, embarrassed for them. It hadn’t occurred to me that they hadn’t been writing regularly as well.

Lulu changed the subject. “So you’re playing in the Shanghai invitational? That’s really wonderful.”

It was: after playing together for six years, my team had finally qualified. Out of four teammates, I’d only ever met one in person before. I thanked Lulu.

“Is there prize money?” she asked.

I told her yes, a little.

“Excellent,” she said, grinning.

Our parents were very quiet. I suspected that they wanted an apology, and also that it wasn’t forthcoming. When Lulu said that she and Zhangwei were planning to move nearby, our mother froze, as though she’d been handed a cracked egg and didn’t know what to do with it.

“He thinks it’ll be good for me to be closer to home,” Lulu said, breaking the silence. “At least while I get used to a normal life again.”

“What can you do out here?” my mother asked stiffly. “Can you find work?”

Lulu tossed her head, and a flash of her old arrogance flared in her. “Yes, Mother. I was the top-scoring student in our year for math, don’t you remember?”

“Maybe Mao Xin could help her get a job,” my mother said. It wasn’t a tactful remark, but then my mother loved Mao Xin, had come to rely on her in a way that reminded me of her relationship with Lulu before she went to college.

“Sure,” I said, with an apologetic glance at Lulu. “Anyway, that’s great news. We’ll have to celebrate.”

She smiled at me, a little sadly. “Thanks, Big Brother.”

Eventually she found work handing out tea samples at the mall, a chain store with neon-green hills in its sign. It was an easy job, and the boss didn’t ask questions about her past. In the meantime, she was learning a lot about tea, she said, about the oxidation process, about the proper way to steep different varieties.

“Wow, they really train you over there,” our father said. In the weeks since her release, he had become a champion government booster, missing no opportunity to point out to Lulu how nicely the roads had been paved since she’d left, how grand the malls were that had been built. “There are so many opportunities for young people now,” he said. It was a new tic of his, and it grated. Earlier that day, as we strolled the neighborhood, he’d taken the chance to point out a set of recently upgraded public toilets across the way. “They even installed a little room where the sanitation workers can rest,” he said. “It has heating and everything. You see what good care they take of all the workers now?”

I rolled my eyes.

“Anyway, it’s temporary,” Lulu said of her job, and that, of course, was what scared us most of all.

I could see that she was planning something. Once, when she was using my laptop, I saw over her shoulder that she had a document open, titled “An Open Letter to the National People’s Congress.” When she got up to use the bathroom, I scrolled hastily through the text, seeing a list of half a dozen names signed, her own and those of a few lawyers and professors—no one I’d ever heard of. I didn’t say anything to her, but later that afternoon I pulled Zhangwei aside and told him what I’d found. He nodded.

“I know,” he said. “Your sister doesn’t change.”

I didn’t know what he meant, but I bristled a little anyway. “She wasn’t like this when she was younger,” I said.

“Of course not, she was too young then.”

“You don’t know what she was like.”

“O.K.,” he said patiently, his eyes on the door behind me, waiting to see if Lulu would walk in. He was always mentally tracking her location, the world’s most devoted bloodhound.

“I mean that. She was smart. She was probably the smartest in our school.”

“And you think she isn’t smart anymore?”

“That’s not what I meant,” I said, but Zhangwei was already flicking the ash from his cigarette and walking away, disappointed in me.

Iflew to Shanghai for the mid-season invitational alone, shrugging off Mao Xin’s offer to accompany me, but when I arrived I immediately wished she were there, just to see the spectacle. The games took place in a stadium downtown, the floor lit up with strips of red and blue L.E.D. lights. The stadium was packed, and as we played in padded seats onstage, headsets on, the crowd waved red and blue glow sticks.

We won two rounds, and went on to trounce the South Korean team in the third. In the background, the crowd was moaning, the sounds mingling with the noise of my own blood as we clicked frantically, sending out great gusts of orange fire. “Never give up! Never say die!” the crowd chanted.

When the games were over, the flashing scoreboard had us in third place. The cameras flocked to the floor, descending on us like black hooded birds. We gave sheepish smiles and said how proud we were, how we’d be back next year to win for sure. Somehow we were ushered onto a podium, beside the other winning teams. They handed us a trophy as silver confetti rained down, great clouds of delicate parallelograms. When I watched the video later, it looked as if we were standing in a hail of razor blades. We hoisted the trophy into the air, all five of us. It wavered and nearly tipped, but the tallest among us righted it and we let it hover there, admiring it.

Four months later, Lulu went back to prison, this time on charges of trying to subvert state power, after she and others had circulated an online petition calling for all government spending to be made transparent. This time the prison was not so nice, and the judge gave her a ten-year sentence. The last time I saw her, she had lost fifteen pounds and looked shrunken, the same size she’d been in high school.

A few years after she was jailed, Zhangwei moved back to his home town to be closer to his parents and got married to someone else. He wrote us a letter apologizing. I threw it away after seeing the return address, but Mao Xin fished it out of the trash and insisted that I read it. “Your sister is a truly rare person, and it is with the greatest sadness that I have to move on,” he’d written. “I’m sorry I couldn’t help her more.” I stood there for a minute, admiring his penmanship, which I’d never seen before. It was elegant, balanced—almost noble, I observed, before tossing the letter out again.

After the Shanghai invitational, our team started competing heavily on the domestic circuit, winning actual prize pools now and again. With Mao Xin’s encouragement, I cut back my hours at the hotel and devoted more time to training. The following summer, we flew to Sydney for the global finals. It was my first time abroad. By then we had fans, even sponsors; we entered the arena wearing identical jumpsuits with the name of an energy drink printed across our chests.

On the plane, we crossed the ocean, heading south. I took out my camera and snapped a photo for my next letter to Lulu. The flight attendants passed out headsets, and I slid one on, suddenly homesick. I closed my eyes and thought of my sister. I prayed for victory, and hoped that she would be proud. ♦
