Many large cities in the United States have an area called Chinatown. It was set up by people who came from China. For example, Chinatown in San Francisco, California, began in 1848. The Chinese immigrants(移民) came to America to look for gold in the 1850s. Then the area they lived in later became known as Chinatown.
Chinatowns were also set up in cities in the western states like Oregon (俄勒冈州) and Washington D. C. during the 19th century. Many Chinese immigrants in these areas helped build the first railroad system across the United States. However, after the work ended, many Chinese moved to the eastern and middle parts of the United States.
Chinatowns can also be found in cities outside the United States. For example, the first Chinese immigrants arrived in London in the late 18th century. They were men who worked for the East India Company. Later, the Chinese immigrants opened small shops and restaurants there.
Today, many people visit Chinatowns. They have special Chinese gates and walking areas for visitors. Chinatowns around the world are not only places where Chinese people live and work, but also places where visitors can learn more about Chinese culture and traditions.
