Because of special history between Taiwan and China, it leads Taiwanese have special national consciousness, which you could hardly find in other countries.
I have seen some people when they talked about their countries, they showed a little bit inferiority. However, when Taiwanese talked about their country, I saw perseverance in their eyes.
Regarding Tzuyu's apologize video, because of waving Taiwan flag, under the pressure from Korea JYP. Triggering the anger of Taiwanese, assisting Tsai Ing-wen winning the election to be the first female president in Taiwan.
I would like to express my thought briefly, even I'm politically apathetic.
Having lived Europe for almost 4 years, I'm missing Taiwan all the time. Sometimes any random video related to Taiwan, I could drop my tear easily.
Every time, when people asked me, where do you come from?
I always said I'm from Taiwan, that is my home. :)
I believe that explains everything.
To argue if you are Chinese or Taiwanese?
It is just meaningless of word games.
