In April 1972, bamboo slips of both Sun Tzu's and Sun Bin's works were unearthed in the Yinque Hills (Lixing, Shandong province). Due to natural erosion, some of the bamboo slips were damaged and difficult to reinterpret. After the initial collection and study by experts, the Cultural Relic Press published a new edition of Sun Bin's Art of War, divided into two volumes, each containing 15 chapters, from the 364 bamboo slips, with a total of 11,000 words.
