Earlier quoted context omitted.
Hong Kong was set as an example how Taiwan can be integrated as a separate economy, separate government and separate everything as long as it is part of China. The reason why it happened in Hong Kong was that the political movement was out of control, you have some members of the parliament saying "fuck China" when they swear to service during the ceremony. It is more about how Hong Kong sees China, not how China see…
This is straight up the official CCP party line you're repeating here. How Chinese people are somehow uniquely unsuited for democracy. The "multiparty democracy system in Taiwan is not seen as a positive thing" by whom? The Taiwanese? The election results from that country have shown quite the opposite.
Taiwan's population is ~23.4 million.
In 2020 there were ~19.3 million registered voters with 74.9% turnout. [1]
In 2024 there were ~19.5 million registered voters with 71.86% turnout. [2]
Note that voter registration appears to be automatic[3] so I believe turnout also represents the percentage of all people 20 years and older who voted.
