@CoffeeVani22446 For historical reasons, during the Liberation War in the 1940s, the Kuomintang was defeated and retreated to Taiwan. The Communist Party of China did not have the ability to liberate Taiwan at that time.
@CoffeeVani22446 In mainland China, more and more people are unwilling to treat Taiwanese people preferentially because of this tendency (of course, many people in Taiwan have not stopped spreading rumors and slandering mainland China, which is also one of the reasons)
@CoffeeVani22446 In Taiwan, the Kuomintang gradually lost power, and the newly came to power Democratic Progressive Party destroyed the national identity of the Taiwanese people, making them gradually think of themselves as an independent country.
