In the tenth year of Qin Dynasty (237 BC), the king of Qin entered Qin to lobby and was appointed as the national coach because his name was. A famous military theorist.

Some people say that Liao Wei is the high foot of Guiguzi and lives a hermit life after graduation. Later, he was recruited by Wei Huiwang and taught him the art of war.

Today's Wei Liaozi has 24 articles with nearly 10,000 words. This book mainly discusses the general view of war, supports just war and opposes unjust war, discusses the relationship between war and politics and economy, and puts forward that "martial arts is a plant, literature is a kind, martial arts is a form, and literature is fine." It is necessary to take agriculture as the foundation of governing the country, and the people are rich and the country is strong. This paper discusses the tactical measures of commanding the army, training and training, perfecting the military regulations, warning the generals and "keeping the people safe" and "defeating the enemy", discusses the tactical problems such as attacking the city and defending the city, and puts forward the positive and negative experiences of 12 in running the army.

On the overall view of war, Liao Wei believed that there were two different wars at that time, opposing the unjust war of killing people and stealing money and supporting the just war of "suppressing chaos and banning Africa". Clearly pointed out: "Every soldier will not attack innocent cities or kill innocent people. Killing fathers and brothers, people's wealth and goods, and children of male and female servants are all thieves. "

Regarding the strategy and tactics of war, Liao Wei emphasized the need to fully understand the war, and pointed out three different but interrelated winning strategies: First, First, Second, Third. I believe that knowing these three ways to win will fully grasp the initiative in the war. He pointed out the importance of overall command in the war. "Power the enemy to judge the generals and then send troops." A general has a heart, and a team leader has a restraint. "Is the correct analysis of the situation of the enemy, carefully choose generals, and then send troops. General and foot soldiers should be as harmonious as heart (brain) and limbs, and become a whole, so as to conduct correct command wisely and tactfully. He advocated that the army must first legislate to govern the army, and the laws must be strictly enforced, so as to be unified and neat, dare to cross mountains and mountains, dare to wade into deep water, and dare to attack and slam, so that "the world cannot fight with it." "Those who violate military discipline and military orders should be severely punished, and generals and soldiers who have surrendered and fled should be severely punished to make them afraid and concentrate on the enemy.

Regarding the relationship between military and politics, Liao Wei compared it to the relationship between the trunk and seeds of plants. The so-called "a soldier, with martial arts as his plant, literature as his seed, martial arts as his face and literature as his interior, can judge the two and know the outcome." It is pointed out that there can be no strong military power without good politics, and military is the means to solve political problems. The author has repeatedly stressed the importance of developing production for the army and pointed out that military commanders should take agriculture as the foundation of governing the country. "The husband is in the field, the wife is in the machine, and the people have nothing to do to save." The people are rich and the country is strong, and the soldiers are solid, so that they can defend and attack.

Liao Wei put forward both positive and negative experiences in running the army with a simple dialectical point of view. The author believes that if we follow the positive experience of 12, we can overwhelm the enemy. Otherwise, it will be crushed by the enemy. The positive experience of 12 is: establishing prestige lies in not easily changing orders, rewarding people in time, adapting to changes in various situations when making quick decisions, and mastering the morale of both sides when defeating the enemy: winning an attack lies in surprise attack, being firm in defending fortifications, not making mistakes lies in obeying the law, not causing trouble lies in being prepared, being cautious lies in preventing minor delays, being wise lies in being able to handle major events and eliminating disasters lies in being resolute; Winning people's hearts lies in modesty.
