The newly discovered copy of this topic, "Xu Guangqi's son was written by my late father in the cloud, and Yushan's view was briefly reviewed by his father", has been criticized by Shan Kan for more than ten articles. The book consists of six articles, the contents and main contents of which are as follows:
General Tactics First, with the title "Hundred-character Tactics in the Art of War" at the end of the volume, namely "Hundred-character Tactics in the Selection and Practice of Wen Ding Gong Ji Yin" by Xu Ermo, namely "Hundred-character Tactics" contained in Xu's genealogy Han Mo Kao. It is called "Hundred Words", but it is actually 15 words. If you count "arm strength" and "camp array" as one word each, there are also 13 words. * * * Divided into three parts: the importance of learning soldiers, the importance of raising soldiers, the importance of teaching soldiers, the importance of learning arts, the importance of choosing a scholar, the courage, the courage, the wisdom, the strength, the skill, the skill and the figure. Each word has its own meaning, and some of them are briefly interpreted, such as "thinking" of "learning from soldiers" is interpreted as "meditating and thinking", "speaking" is interpreted as "learning all over the world" and "nurturing" is interpreted as "treating the heart and qi". Some of them have not been explained, but they are concise, such as summarizing the "essentials of the art of war" into eight words: "attack, defense, shape, potential, strangeness, correctness, emptiness and reality"
The Second Style, with the title Art of War at the end of the volume, includes three articles, namely, Training Style, Training Style and Form Style, which is the concretization and systematization of Xu Guangqi's "Selecting and Training Hundred Characters Tactics" based on his training practice. The "Art Training Rules" emphasizes the importance of art training, and specifies various skills and specific requirements that soldiers need to practice. It is pointed out that "the long-distance training device shoots the bow and arrow first", "the long-distance training device shoots the wolf and bears the spear first" and "the short-distance training device has one knife, two sticks, three sickles and four palladium, all of which are more than nine feet long." Shu Wu Tiaoge is subdivided into Wu Yi, Wu Hao, Wu Yue and Wu Shu, which lays down the rules for the organization, management and discipline of the army, and stipulates that five soldiers and four captains of the army are bound by each other and it is strictly forbidden to escape. The "Form and Name Rules" stipulates the command orders and signs of the army, including service badges, flags and golden drums. Emphasize that "all people are one", "all people have one ear, one eye and one heart".
