孙膑兵法

孙膑, said to be a descendant of 孙武, served the state of 齐 in the 4th century BC. His name comes from the punishment 膑, removal of the kneecaps, which his jealous fellow student 庞涓 had inflicted on him; Sun Bin later beat him at the battles of Guiling and Maling. The book is listed in the Han imperial catalogue but was lost soon after.

In 1972 bamboo slips of this book and of the 孙子兵法 were dug up together from a Han tomb at 银雀山 in 临沂, Shandong. The find settled a long argument: some scholars had held that Sun Wu and Sun Bin were one man and the two books one book.
