This poster depicts Mao giving a lecture to Shanxi and Hebei Daily newspaper's editors. Originates from an oil painting developed by Su Zhou, Wang Ying Chun and Yang Li Zhou. The speech Mao gave to these editors was on the philosophy of doing things should have its angels, and sometimes things should be done one way and other items things can be done another way, an analogy derived from the Strategy of War by Sun Zi. Published by People's Fine Art publishing house, printed by People's Printing Company, and XinHua Bookstore in May 1977. The price of the poster was 14 cents. Size: 12.5" by 15".
