She was not from any part of China, but from a country thousands of miles to the south, and in that country she had grown up in a small town in the far north-east. It is a region that is poor and remote, so she is used to people thinking of her as inferior, even in her own country. In her small town the way of life had not changed very much for fifty years, and would probably never change. Visitors from the capital city used to call it charming, but they didn’t have to live there. It was not a place for dreams and ambition, and so Phoebe did not dream. She did what all the other young boys and girls did when they left school at sixteen: they travelled across the mountain range that cut the country in two to find work on the west coast, moving slowly southward until they reached the capital city.

      Here are some of the jobs her friends took in the year they left home. Trainee waiter. Assistant fake-watch stall-holder. Karaoke hostess. Assembly-line worker in a semiconductor factory. Bar girl. Shampoo girl. Water-cooler delivery man. Seafood-restaurant cleaner. (Phoebe’s first job was among those listed above, but she would rather not say which one.) Five years in these kinds of jobs, they passed so slowly.

      Then she had some luck. There had been a girl who’d disappeared. Everyone thought she was in trouble – she’d been hanging out with a gangster, the kind of big-city boy you couldn’t tell your small-town parents about, and everyone thought it wouldn’t be long before she was into drugs or prostitution; they were sure of it because she had turned up one day with a big jade bracelet and a black eye. But from nowhere Phoebe received an email from this girl. She wasn’t in trouble, she was in China. She’d just decided that enough was enough, and left one morning without telling her boyfriend. She’d saved enough money to go to Hong Kong, where she’d been a karaoke hostess for a while – she was not ashamed to say it because everyone does it, but it was not for long – and now she was working in Shenzhen. She was a restaurant manager, a classy international place, not some dump, you know, and she was in charge of a staff of sixteen. She even had her own apartment (photo attached – small but bright and modern with a vase of plastic roses on a glass table). Thing is, she’d met a businessman from Beijing who was going to marry her and take her up north, and she wanted to make sure everything was OK at the restaurant before she left. They always needed good waiting staff at New World Restaurant. Just come! Don’t worry about visas. We can fix that. There were two smiley faces and a winky one at the end of the email.

      Those days were so exciting, when they emailed each other several times a day. What clothes shall I bring? What is the winter weather like? What kind of shoes do I need for my uniform? Each email that arrived from China made Phoebe feel that she was one step closer to lifting herself up in the world and becoming someone successful. It made the hair salon where she was working at the time seem so small – the clients were small people who did not realise how small they were. When they said to her, Hey, Phoebe, you are not concentrating, she just laughed inside because she knew that very soon she would be the one giving them orders and leaving them tips. She was going to experience adventures and see things that none of them could even dream about.

      It took her a few weeks to get enough money together for the ticket to Hong Kong plus a bit extra to get her to Shenzhen, but from then on it would be plain sailing, because she had a job lined up and she would stay with her friend for the first couple of months until she found her own place. She didn’t need all that much money, she would start making plenty once she got there, her friend assured her. From then on anything was possible. She could start her own business doing whatever she wanted – some former waitresses at the restaurant were already going around in chauffeur-driven cars just a year after they quit their jobs. New China was amazing, she would see for herself. No one asks too many questions, no one cares where you are from. All that counts is your ability. If you can do a job, you’re hired.

      People say that it is hard to leave their lives behind, and that when the time comes for you to do so you will feel reluctance and longing for your home. But these are people with nice lives to leave behind. For others it is different. Leaving is a relief.

      The emails continued, full of !!! marks as usual, but they were less frequent, and finally, at the internet café near East Tsim Sha Tsui station, waiting for the train to Shenzhen, Phoebe logged on for the first time in four days to find not a single email from her friend. Not even a short message that said, Hurry, too excited, followed by lots of smileys. When at last she got to Shenzhen it took her some time to locate the restaurant. The sign was proud and shiny. New World International Restaurant, it read above twin pillars of twisted gold dragons – Phoebe recognised it from the photos her friend had sent her. The menu was in a glass case outside, a sure sign of a classy joint. But as she approached, Phoebe’s heart began to experience a dark fluttering in her ribcage, the way she imagined bat wings would feel against her cheek. It was a sensation that would stay with her for the rest of her time in China. The glass doors were open, but the restaurant inside was dim even though it was the middle of the afternoon. When she stepped inside she saw an empty space without any chairs and tables. Part of the floor had been ripped up, and on the bare concrete she could see messy patches of glue where carpets had once been laid. There was a bar decorated with scenes of Chinese legends carved in bronze, cranes flying over mountains and lakes. Some workmen were shifting machinery and tools at the far end of the restaurant, and when Phoebe called out to them they seemed confused. The restaurant had closed down a few days ago, soon it would be a hotpot chain. The people who worked there? Probably just got jobs somewhere else. No one stays in a job for long in Shenzhen anyway.

      She thought, This is not a good situation.

      She tried calling her friend’s mobile phone number, but it was dead. This number is out of use, the voice told her, over and over again. Each time she dialled it was the same. This number is out of use.

      She checked how much money she had and began
