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 thousand 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 like 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.
