Ma Bufang
Ma Bufang attacked and demolished a Tibetan Buddhist monastery in Rebgong in 1939, one of the oldest in Amdo. Ma Bufang sent his army to destroy and loot the Tsanggar Monastery in 1941; his forces expelled the monks. It was not until the Communists took power that the Monastery could be rebuilt; the monks returned in 1953. Many of the monasteries attacked by Ma Bufang were associated with the Ngoloks.
