> Your take also ignores the fact that unification is Chinese core value

It seems to me that you are saying that a contemporary political position (that Taiwan should be ruled by the same government as mainland China) is in fact a "core value". Unity can be a value, but the political position that the island of Taiwan is an integral part of China, and China can't be unified without it, is not. That's the position which is encouraged by propaganda and government rhetoric, and mirrors similar positions with regards to, for example, Tibet.
