Liu Shaoqi's How to be a good Communist (论共产党员的修养) was published in 1939. The treatise was based on a series of lectures he had given in Yan'an. It became very influential, and was reprinted many times. During the Cultural Revolution, the book came under heavy attack, just like its writer.

Above, in yellow characters, a Mao quotation: All mistaken ideas, all poisonous weeds, all monsters and demons, all must be criticized, they can not be allowed to spread freely (凡是错误的思想, 凡是毒草, 凡是牛鬼蛇神,都应该进行批判, 决不能让它们自由泛滥).
