Most immigrants come and live in cities, where there are other people from their community. In the past they mostly settled in seaports. Immigrant communities in London, Liverpool and Glasgow are very old, and were started by sailors. Chinese people moved out of the cities and started laundries and restaurants, often in small country towns where they were the only immigrants. George Formby made several songs about "Mr. Wu", a Chinese laundry man in the 1930s.
