Li has a profound exposition and thorough analysis of singularity in Question. He quoted the "Grip the Odd Sutra": "Eight arrays, Four Righteousness and Four Oddness", which shows that Oddness is originally a tactic of square matrix transformation. There are four "positions" or "fields" in the phalanx (that is, positions of combat troops), and four "idle places" or "virtual places". The troops fighting in the "battlefield" are "regular troops"; The troops that use "virtual land" for maneuvering are "raiders". It believes that strangeness and strangeness can be transformed into each other, and puts forward that "those who are good at using troops are all right about strangeness, making the enemy unpredictable, so power will win and strangeness will win." "Zheng Qi only exists in people and becomes a god, so he is promoted to heaven." Explain military issues such as advancing and retreating, attacking and defending, being outnumbered, becoming a general, forming a formation, and training. From the viewpoint of singularity, Sun Tzu's singularity theory has been greatly developed. For example, it points out: "every soldier is right to move forward, but it is strange afterwards"; "It is right to fight first, and then it is a surprise victory"; "The public's correctness will be surprising." "Who will, not surprisingly, this ShouJiang also; If there is no righteousness, then there is a fight; Odd is all, Kuninosuke also ",etc. It closely links the odd with the false and the obvious, and points out that "the odd leads the enemy to be false." If the enemy is real, then I am positive; I will be surprised if the enemy is weak. ""but teach the generals to be singular and correct, and then know the reason. " "So its shape, to show the enemy, not me; It is not surprising that the winner will attack the enemy with his right hand. This is called odd-positive phase transition. " "Being human and not being human is the acme of singularity. "
Li attaches great importance to the problem of array training. It is advocated that the troops should be trained according to the actual needs, so as to achieve "fighting without chaos", "round without dispersion" and "never leaving" in the battle. It attaches great importance to training methods and thinks that "if you teach well, you will be happy to use it;" Teaching is no good, although it is useless to blame. "The emphasis is on training according to the different characteristics of the troops." Han garrison should be his own law, and exile should be his own law. Teaching and learning are different, so don't confuse them. "It also puts forward the training procedures from individual soldiers to teams, from teams to large forces, that is, from martial law to team law and array law. The square matrix and cyclic matrix are clearly expounded. Especially for the six-flower array created by Li Jing, it is clearly pointed out that it is based on Ge Liang's eight-array method. " The square outside and the circle inside are six flowers, with the customs number. ""where the team is formed, it is ten steps apart; Twenty steps from the resident team to the front team; Every other group, set up a group. Fifty steps forward. When the horn sounded, all the teams dispersed, but they were all within ten steps. On the fourth horn, the cage gun knelt down. So beat the drums, three calls and three strikes, and control the enemy's changes in thirty to fifty steps. After Ma Jun left, it was also a temporary holiday. How to meet the enemy when the front is right and the back is strange. Drum up again, you will be surprised before you get it right, recruit the enemy again, and wait for the gap. These six kinds of flowers are all natural. "
Li's Gong Wei Wen Dui summarizes the origin of the ancient art of war, and holds that the ancient art of war can't be divided into three categories and four categories, namely: "The squire seeks eighty-one articles, so-called inexhaustible; Article 71 of Tai Gong Yan cannot be poor; The eighty-five articles of Thai Gong Bing must not be poor in wealth. These three doors are also. " "Tactics is a kind, the situation is a kind, Yin and Yang and skills are two kinds. These four kinds are also. " It comments on and develops the important ancient art of war, which contains many original opinions. For example, the explanation of Sun Tzu's "insufficient rules, more than enough attack" is not limited to Cao Cao's old theory, but criticizes them for "not knowing the law of attack and defense" with their strength. Pointed out that "the enemy is invincible, then I am self-controlled; When the enemy can win, attack him. It is not based on strength. " On the issue of attack and defense, it puts forward many valuable views, such as "attack is an opportunity for defense, defense is an offensive strategy, and the same result is only victory." "Attackers, not only attack its city, attack its array, but also attack its heart. It remains to be seen that the defenders will not only complete their walls and strengthen their array, but also defend our spirit. " Wait a minute.
Li's Questions and Answers also contains rich thoughts of simple dialectics. It believes that the victory or defeat of the war is caused by many factors and cannot be attributed to a single reason. "The military strategists win or lose, and the situation is different. It cannot be done overnight." It also believes that everything is developing and changing, and its strength, advantages, subject and object are all changing. "'Because food is an enemy' is to change customers." If you are hungry enough, you can work hard "is to turn the host into a guest." It attaches importance to personnel and opposes superstition, pointing out that "future generations will fall into tricks and lose more" and "its success lies only in personnel". However, it does not advocate abandoning the number of yin and yang, and thinks that this is a cunning technique of "making greed stupid".
