well,
1, Qianglong Emperor published a speical constitution of Tibet in 1790s.
2,Tibet indeed enjoyed semi-autonomy or even entire autonomy before 1950,but it can deny that TIbet was a part of CHiense empire.It was one of “inner vassals “ of Chinese empire,just like Mongolia.
...otherwise Britain would not deal tibet business through Beijing in 19th century.
3,”Tibetans have maintained ethnically separate bloodlines and language for their entire history “ just proves how generously Chinese treats the tradtional culture.
4,Amdo and Kham had been directly ruled by CHinese emperor for hundreds of years at least.
In part of Amdo and Kham, Han-chinese started to settle there when Roman Republic even still struggled to fight against Carthage.
When Roman fought against Carthage,where was Tibet?
That's funny. If they had "entire autonomy" how could they be a part of China? Apparently your education didn't include logic.
It was one of “inner vassals “ of Chinese empire,just like Mongolia.
Except when Mongolia conquered China and China was an inner vassal of Mongolia...and put under the authority of Tibet. LOLOL
