Taiwan is not part of China and it was never before. Thirty-five years ago, I thought my co-worker was from China, so when I asked him if he was Chinese, guess what? He got very upset and told me he was from Taiwan and Taiwan wasn't part of China. That was 35yrs ago, not today.
Huge difference between Taiwan elected democratic system and the Chinese Communist bandits. Taiwan should be proud of themselves and I still wonder why there are some people in Taiwan are Pro China Communist and yet refuses to give up citizenship and move to China.
