Sun Bin's Art of War is a renowned Chinese treatise on military strategy that dates back to the Warring States period, an era of political instability and warfare in ancient China. It is credited to Sun Bin, who was believed to be a descendant of the famous military strategist Sun Tzu. Sun Bin served as a military advisor in the Qi state during this period and is said to have authored this piece on military tactics. Historical records from the Han dynasty suggest that the original text of Sun Bin's Art of War comprised 89 chapters, accompanied by four volumes of illustrations. Unfortunately, the original work was lost by the end of the Eastern Han dynasty. While Sun Bin's Art of War and Sun Tzu's The Art of War share a similar name, they are distinct works by different authors. Source: Wikipedia (en)
