Are there many Hong Kong people in Britain?

There were several waves of emigration to Britain in the history of Hong Kong, one in the 1970s, which seemed to be the period of reform and opening up. Another time was 1997 Hong Kong's return. Those who didn't want to return came to Britain ... in short, a large part of those who had stable jobs here immigrated to Britain in their early years. Hong Kong people are everywhere. These are all from my friends in Hong Kong, who have been here for a long time.

Either visa-free or it is easy to get a visa.
