What's the consequence of criticizing the CCP in China?
Which law it will violate?
There's a more famous woman criticizing the CCP in China(https://en.wikipedia.org/wiki/Fang_Fang), any consequence? No, no consequence, then why ordinary people are afraid of criticizing the CCP in China? especially for only offline investigation rather than published publication?
Taiwan's official name is Republic of China(https://en.wikipedia.org/wiki/Taiwan), it's not China/Taiwan issue, it's China Civil War.
Just like Democratic People's Republic of Korea and Republic of Korea(https://en.wikipedia.org/wiki/Korea), the two China and the two Korea will unify finally.
