Wujing Zongyao
The "Wujing Zongyao" was one of 347 military treatises listed in the biographical chapters of the History of Song (1345 AD), one of the Twenty-Four Histories. Of these 347 different military treatises from the Song period, only the "Wujing Zongyao", the "Huqianjing" (Tiger Seal Manual) of Xu Dong in 1004 AD, and fragments of similar works found in the later "Yonglo Datian", have survived. The original text of the "Wujing Zongyao" was kept in the Imperial Library while a number of hand-written copies were distributed elsewhere, including a copy given to Wang Shao by Emperor Shenzong of Song in 1069 AD.
