Tai O
When the British came to Hong Kong, Tai O was known as a Tanka village. During and after the Chinese Civil War, Tai O became a primary entrypoint for illegal immigration for those escaping from the People's Republic of China. Some of these immigrants, mostly Cantonese, stayed in Tai O, and Tai O attracted people from other Hong Kong ethnic groups, including Hoklo (Hokkien) and Hakka.
