呉起
The writings of Wu Qi were known to be in wide circulation by the late Warring States period. The assertion of the book's early popularity is based on the comment, from the "Han Feizi", that "Within the borders everyone speaks about warfare, and everywhere households secretly store away the books of Sun and Wu." The "Shiji" corroborates this information. The "Wuzi" continued to be studied both by famous Han dynasty figures, and by those in the Three Kingdoms period. The record of continuous attention supports the view that was continuously transmitted from the Warring States until at least the Three Kingdoms period.
