Li Xiucheng
In 1963 he wrote an article on Li Xiucheng, which for the first time gave him Mao's approval for his radical approach. He became a member of the Board of Editors of the Party journal "Red Flag". There, on 8 December 1965, following Yao Wenyuan's "Criticism of "Hai Rui Dismissed from Office"", he published the article "Study History for the Revolution", in which he criticised the most famous Historians of the time by denouncing their Historism as Capitalist. The article was mainly aimed at Jian Bozan but did not name him.
