Just adding a bit of geography here...
Hong Kong is not located in Taiwan.
Hong Kong is a formerly British colony and was handed over to China some years back.
Hong Kong is located in the south-east of China and almost an island.
Taiwan is an island located east of China.
IIRC opponents of Mao fled to this island and established a democracy there.
China never accepted Taiwan as a separate nation and wants it back in their Reich.
