The Art of War by active 6th century B.C. Sunzi

3. LI CH’UAN of the 8th century was a well-known writer on military

tactics. One of his works has been in constant use down to the present day. The _T’ung Chih_ mentions "Lives of famous generals from the Chou to the T’ang dynasty" as written by him. [42] According to Ch’ao Kung-wu and the _T’ien-i-ko_ catalogue, he followed a variant of the text of Sun Tzŭ which differs considerably from those now extant. His notes are mostly short and to the point, and he frequently illustrates his remarks by anecdotes from Chinese history.
