Tifayifu (simplified Chinese: 剃发易服; traditional Chinese: 剃髮易服; lit. 'shaving hair and changing costume') was a cultural assimilation policy of the early Qing dynasty as it conquered the preceding Ming dynasty. In 1645, the Tifayifu edict forced Han Chinese people to adopt the Manchu hairstyle, the queue, and Manchu clothing.
The edict specifically applied to living adult men who did not fall in the stipulated exceptions. In 1644, on the first day when the Manchu penetrated the Great Wall of China in the Battle of Shanhai Pass, the Manchu rulers ordered the surrendering Han Chinese population to shave their heads; however, this policy was halted just a month later due to intense resistance from the Han Chinese near Beijing. Only after the Manchu captured Nanjing, the southern capital, from the Southern Ming in 1645 was the Tifayifu policy resumed and enforced severely.
