 In their effort to discredit Tibetan Buddhism, the People's Republic of China as well as Chinese nationalists in the Republic of China make frequent and emphatic references to the historical practice of human sacrifice in Tibet, portraying the 1950 People's Liberation Army invasion of Tibet as an act of humanitarian intervention.According to Chinese sources, in the year 1948, 21 individuals were murdered by state sacrificial priests from Lhasa as part of a ritual of enemy destruction, because their organs were required as magical ingredients.The "Tibetan Revolutions Museum" established by the Chinese in Lhasa has numerous morbid ritual objects on display to illustrate these claims.
