I don't know if things are different now, but when I went to school in HK a long time ago, most Chinese people in Hong Kong I talked to felt Taiwan should be part of China.
I encourage everyone who has not done so to have a closer look at Taiwan's history.
The situation is markedly different from Hong Kong.

Of course it's very different. Taiwan was a right wing dictatorship which ruled by terror, they don't have much of my sympathy.
