As its name implies, Tang Wenliquan is a collection of comments on war by Li Shimin and Guo Wei Li Jing of Emperor Taizong. However, since the Northern Song Dynasty, it has been put forward that "jing yuan said that it was handed down by Wang ... Li's Wenquan was written by Ruan Yi" and why he put forward in Moon Hee in Chun Zhu that "the late king (according to where to go) said that Liu Tao was not written by Taigong ... and he suspected that Li's Wenquan was not. According to Chen Hehe's opinion, Chao's Reading the Secretary, Chen's Notes on Solving the Problem of Zhai Zhi, Wang's Notes on Changing Zhai, Wang's Preface to the Collection of Art of War, and Xiang Pu's Notes on Xie Lu Wen Dui, etc., it is believed that the official document Dui was written by Ruan Yi. Another view denies Ruan Yi's forgery. For example, Ma Yuan Duanlin said: "The theory of correction, such as the immortal writing a letter to Wang Zhen, is clearly seen in National History, but it is not Ruan Yi's disguise." Yao Jiheng said in the Qing Dynasty, "The inheritors of this world should be regarded as the final version when they were still sects. Because the religious sects at that time had an edict that "military officers and assistants could not understand", most of them were swearing. If Ruan Yi wrote it, it would be wrong. If you want to read this book, don't write it unless you are satisfied with it. And this book has been done all over the world, but another book can't? "There is also an opinion that denies Ruanyi's forgery and Gong Wei's writing. For example, Ming Hu Yinglin said, "This book is neither Gong Wei's nor Ruan Yi's. It should be regarded as the legacy of Tong Dian written by Du You in the late Tang Dynasty and early Song Dynasty. "According to modern research, seven kinds of art books were popular in the early Song Dynasty, and seven kinds of art books, such as Li Wen, were revised by Yuanfeng for three years and awarded as martial arts classics. As a martial arts and martial arts teaching material, it is said that Song Renzong Tiansheng (1023 ~ 103 1) is the only scholar. Say, "The words are shallow and vulgar, and the strategist is the most dead. "... Li's Scholars at the end of the Tang Dynasty and the beginning of the Song Dynasty was even more biased when compiling the legacy of Zhenguan monarch and minister, Du You's Tongdian and Fu's Yanerkou. The fair evaluation is: "Li is right", "The gains and losses of prosperity and abolition, the facts of the matter, the tactics of the soldiers and the brilliance of the achievements can all be learned by future generations." Q&A in Gong Wei is very detailed and really great. ""His book is wonderful, which refers to the painting of offensive and defensive, the change of subject and object, and the income of the strategist when he is indifferent. "Look at the book, the above comments dare not compliment. Although Li Ti may not be the final version of Li Jing, it was compiled by hermits who were familiar with the deeds of Emperor Taizong and Li Jing according to the comments of Tang and Li Lunbing, and the specific time of writing was uncertain. However, according to the spread of seven kinds of military books in the early Song Dynasty, the lower limit should be before the Five Dynasties.
