London's Chinese community   dates back to the 18th century, when a small number of Chinese sailors   moved to the city to work in Lime house, east London. As time went on, other Chinese people came to this area and Lime house began to be known as "Chinatown". At the start of the 20th century, there were just 545 Chinese people in Britain. However, this situation changed greatly after the Second World War. At this time, many farmers in Hong Kong lost their jobs, and decided to move to London. In the 1950s, a small Chinese restaurant opened in central London. Many British people visited it and said that Chinese food was wonderful. Suddenly, Chinese restaurants started opening in every part of the city. Instead of too little work, the new Chinese immigrants   now found that they had too much. Most of the new immigrants enjoyed their life and the chances they were offered. Many asked their friends and relatives to join them from their hometowns, and a lot of families were reunited again at this time. As time went by, London's Chinese community became more and more successful. The sons and daughters of the first restaurant workers, encouraged by their parents, studied very hard at school and university. And most of them could get highly-paid jobs. As a result, increasing numbers of Chinese families left Chinatown and moved to the more expensive places.
