破四旧
The Four Olds or the Four Old Things () was a term used during the Cultural Revolution by the student-led Red Guards in the People's Republic of China in reference to the pre-communist elements of Chinese culture they attempted to destroy. The Four Olds were: Old Ideas, Old Culture, Old Habits, and Old Customs (Chinese: Jiù Sīxiǎng 旧思想, Jiù Wénhuà 旧文化, Jiù Fēngsú 旧风俗, and Jiù Xíguàn 旧习惯). The campaign to destroy the Four Olds began in Beijing on August 19, 1966 (the "Red August", during which a massacre also took place in Beijing), shortly after the launch of the Cultural Revolution.
