People have asked if the people in Hong Kong speak with a British accent.
The answer is almost certainly not many, as most of the Hong Kong population are not British..
According to the 2016 census, 92% of the Hong Kong population is ethnic Chinese, and most of the locals speak Cantonese or Mandarin, both being Chinese dialects.
Many of the British in Hong Kong probably do have one of the British accents, (Manchester, Birmingham, London, Cornwall, Yorkshire, etc., or maybe Scottish or Welsh..). But there are only about 33,000 of them, from a total of 7.5 million people in the country.
