As you walk into Chungking Mansions, you might think that you are in another country. There are people of many different nationalities, some wearing traditional dress, and the smell of exotic food fills the air. Only a small number of local teenagers live there. But on the 16th floor is Christian Action's Chungking Mansions Service Centre. The centre is like a home to asylum seekers, many of them from Africa and South Asia. It provides them with food and clothing, books, toiletries and internet access. Living on meagre subsidies, the asylum seekers - who are staying illegally and cannot work - are outcasts. Life is particularly tough for young asylum seekers who arrive in the city with no money, friends or family. 'It's never easy to be a teenager, no matter which country you're from or what your situation is,' said Sarah Cornish, assistant manager of the Humanitarian Services (HK) Department of Christian Action. 'And they [teenage asylum seekers] have to act like adults. They have to be very responsible, and they have to manage their money. 'They have no parents to take care of them - maybe their parents were killed, which is why they're here. They have to recover from all the terrible things that happened to them.' Bob (not his real name) is a tall and slender African asylum seeker. He is a Form One student at an English-medium government school. 'There are so many problems [living in Hong Kong],' said Bob. Bob has stayed in several shelters, including one for street sleepers, since he arrived two years ago. 'I didn't know where to go,' he said. Christian Action is trying to provide Bob with a better living environment. According to Ms Cornish, many teenage asylum seekers feel lost and don't know how to get help when they first arrive. Hong Kong teenagers may not understand their plight. '[Imagine] you don't have a home, a family or constant care. You move from home to home and stay with different people,' said Ms Cornish. Bob cannot afford to eat his favourite food every day. 'He misses his culture and his home; he wants to eat African food,' said Ms Cornish. But Bob is looking forward to a brighter future. His favourite subject is English - which he couldn't speak at all when he first came to Hong Kong. He has also made many friends and plays football with local students during lunchtime. 'I like English because I want to go to the UK. I don't like America. It is very dangerous,' said Bob, who wants to set up a motorcycle business in future. Ben (not his real name) is a South Asian refugee who came to Hong Kong with his family two years ago. The teenager also has high hopes for his future - he wants to be an engineer. He is enrolled in the Initiation Programme - a six-month, government-funded scheme for newly arrived children in Hong Kong. 'His life should not stop. He has to study, get good grades, qualify and start working. We want refugees to have good opportunities in the future, and that's why schooling is so important. Ben does his homework every night,' said Ms Cornish.
