The Three Strategies of Huang Shigong is a treatise on military strategy that was historically associated with the Taoist hermit Huang Shigong and Han dynasty general Zhang Liang. Huang Shigong gave this treatise to Zhang Liang, that allowed Zhang to transform into an adept statesman and powerful war theorist. The treatise's literal name is "the Three Strategies of the Duke of Yellow Rock", based on the traditional account of the book's transmission to Zhang. Modern scholars note the similarity between its philosophy and the philosophy of Huang-Lao Daoism. It is one of China's Seven Military Classics.[1]
