In August 1966, the 11th Plenum of the CCP Central Committee had ratified the 'Sixteen Articles', a document that stated the aims of the Cultural Revolution and the role students would be asked to play in the movement. After the 18 August rally, the Cultural Revolution Group directed the Red Guards to attack the 'Four Olds' of Chinese society (i.e., old customs, old culture, old habits, and old ideas). For the rest of the year, Red Guards marched across China in a campaign to eradicate the 'Four Olds'.
