Questions and Replies between Tang Taizong and Li Weigong

Rather than claiming to originate its own strategy, Questions and Replies frames itself as a survey of earlier, more widely recognized works, discussing their theories and contradictions according to the writer's own military experience.

[3] Unlike other military classics, the history of Questions and Replies has not benefitted from any significant archaeological discoveries, so the date of its composition can only be inferred by surviving historical records concerning the treatise.

A major work (the "Dong Tian"), completed in the eighth century AD, quotes Li Jing extensively, but never once mentions "Questions and Replies".

Assuming that this Li Jing Bing Fa was an edition of Questions and Replies, the existence of the book precedes the supposed date of Yuan Yi's forgery by ten years.

Skepticism that every living general and military scholar could have been deceived by a very recent forgery also fails to support the theory that Questions and Replies was forged by Yuan Yi.
