@Vampire@hexbear.net: I'd like to recommend the whitepaper published by the State Council Information Office of China in 2021, "Tibet Since 1951: Liberation, Development and Prosperity": http://www.news.cn/english/2021-05/21/c_139959978.htm

It's a long read but most of the questions brought up in your comments here can be found in the first 3 sections. Maybe it will clear up some of the inaccurate presentation of history like "Tibet was separate from China before 1720", "Then it was independent 1912-1950". Feel free to question the Chinese government if you believe that certain facts presented in the whitepaper are wrong, and bring your relevant authoritative sources to refute them.
