At present, I am not yet able to provide an answer to the questions you raised; I will need to study them further. If you are collecting materials, that is very good—please gather information from both positive and negative perspectives. It would be most helpful if you could prepare a concise explanatory note for me. I wonder whether the comrades in the Literature and Art Office have time to assist with this?Respectfully,Mao ZedongApril 17Documents and Research (Collected in 1981)Published by the Central Party School Press of the CPC, 1983Letter to Ouyang Shan and Cao Ming, No. 39
