         Chinatown is the name given to an area in the middle of London. It is just between Leicester Square

and Shaftsbury Avenue. Gerrard Street is at the center and is the most important street in the area. There

is a large Chinese community (社区) with a lot of Chinese restaurants, Chinese supermarkets and shops in

this street.

         In the 1950s, it was a poor area and everything was very cheap. At the same time, the world rice

market changed and thousands of farm workers in Hong Kong lost their jobs. They began arriving in London

to look for work. They found jobs in the restaurants in this area. Many British people liked Chinese food, and

the restaurants were popular.

         These restaurant workers often worked 17 hours a day and had no time to learn English. As more

Chinese arrived, more shops and businesses grew up. Wives came and joined their husbands and children

came and joined their fathers. The community grew, and Chinatown was born.

         In the 1970s and 1980s, British-born Chinese started to have a better education and this brought

economic (经济的) success to the area. Many families moved out of Chinatown, and there was more space

for businesses. Gerrand Street became a street only for visitors and was soon a popular place for tourists.

        Now everyone knows about London's Chinatown. During the Chinese New Year, the streets are seen

with flags and thousands of Chinese go into the streets. For most of the year, though, Londoners and tourists

go there mainly for the food in the Chinese restaurants. The best restaurants are the ones where the Chinese

eat.
