There’s a lot of layers there, Han people have been settling in Taiwan since the 17th century and this originally Taiwanese-speaking group makes up about 70% of people in Taiwan. They don’t consider China their homeland anymore than Americans do the UK.
Han people who came with the fleeing KMT government are more directly tied to China, but even they have been largely Taiwan-ized politically since the democracy and identity movements of the 1980’s. Which is to say, very very few people in Taiwan see China as a homeland these days.
