The book "Lu's Spring and Autumn Annals" was compiled by Lv Buwei, the prime minister of Qin Dynasty, who gathered all the guests. This book was written about 239 BC. As for the process of the book "Lu Chunqiu", according to Records of the Historian and Biography of Lv Buwei, during the Warring States Period, Wei Youxin had Ling Jun, Chu had Shen Jun, Zhao had Ping Yuanjun and Qi had Meng Changjun, all of whom were famous minions. When Lv Buwei was in the State of Qin, he felt it was a shame that he was not as good as four children because of the strength of the State of Qin, so he made great efforts to treat him well and raised 3,000 people. At that time, there were many debaters, such as Xun Qing and others, whose titles were world-famous. Lv Buwei also asked his disciples to write down their own knowledge and set it as Eight Views, Six Theories and Twelve Dynasties. * * * has more than 200,000 words, thinking that it can prepare the theory of everything in the world. It is named "Lu Chunqiu" and published in Xianyang City Gate. The princes and tourists can increase or decrease by one. Lv Buwei also confidently declared in the book Preface: "People in the 12th century managed chaos, so they knew good or bad luck in life and death. If you go to heaven, the place where you are inspected, and the person who is in the trial, if so, you will be omnipotent. " From this point of view, the writing of Lv's Spring and Autumn Annals is the product of the cultural and ideological struggle with the princes, which may contain the intention of making theoretical preparations for the unification of Qin. The thought of "Lv Chunqiu" is a summative criticism of the thoughts of pre-Qin philosophers. The article "Parr" said: "It is expensive, Confucius is expensive, Guanyin is expensive, Liezi is expensive, Chen is expensive, Yang is expensive, Sun Bin is expensive, and Ni Liang is expensive." It believes that these different concepts should be unified. "One rule, the difference is chaotic; One is safe and the other is dangerous. " ("Bubu Er") Only when the thoughts are unified can we "go our own way, be clumsy, and do our best, like a hole. "The process of unification is actually the process of critical absorption. Therefore, Lu Chunqiu reformed, developed and sublated all his thoughts. For example, Confucianism advocated the maintenance of monarchical power, which was absorbed by Lv Chunqiu, but it appeared in a unique way. Advocating the new "son of heaven", that is, establishing a feudal centralized state. It reads: "This week's room disaster, the son of heaven is not seen, chaos is greater than no son of heaven." ("Listen"): "There must be a son of heaven in the world, so there is one, and the son of heaven must hold it, so it is also. One rule and two chaos. " (Zhi Yi)

Confucius advocated maintaining the unity of the Zhou Dynasty, but did not emphasize the issue of autocracy. Lu Chunqiu, on the other hand, has the concepts of "upholding one" and "keeping one". "Holding one" and "holding one" are centralization. This is the development of pre-Qin Confucianism. Another example is Mohist thought. Lu's Spring and Autumn Annals agreed with the concept of "festival burial" advocated by Mozi, so it criticized the atmosphere of heavy burial at that time: "The more extravagant, the more worried the dead are, and the living must respect each other." Luxury is glorious, frugality is humble, not to die, but to be praised by the living. But Mozi advocated "non-attack", that is, opposing war. "Lu's Spring and Autumn Annals" refuted this: "If you don't attack Tao, you won't punish injustice. If there is no way to attack, it will be a great blessing and benefit. Those who are forbidden are just and righteous, and Tang and Wu are also guilty. " (Zhen Luan) Lu's Spring and Autumn Annals advocates "righteous soldiers". "Just arrived, and the people of neighboring countries returned to the running water. If the people of the country respect their parents, they will win the people from afar, and the soldiers will not be ready, and the people will serve. " (Huai Chong) Lu Chunqiu believes that it is meaningless and wrong to blindly oppose war. A just war, that is, a war of "attacking injustice without morality", can not only eliminate violence, but also win the heartfelt support of the people. In fact, this is a defense for Qin's war to unify China.

On the issue of material origin, Lu Chunqiu accepted the "essence" theory of Song Yin School and reformed it. Song Yin School believes: "Everything is fine, and it is a profession. There are grains under it and stars on it." And "Lu's Spring and Autumn Annals" said: "Everything is made in Taiyi, and it is transformed into Yin and Yang." (Da Le) That is to say, "Taiyi" is the origin of all things, and everything in the world originates from "Taiyi" and changes from Yin and Yang. What is "Taiyi"? It said: "Those who are also Tao can't see, hear or form ... Those who are also Tao can't form or be named. Strong for it, it is called too one. " Tao is "Taiyi" and "Taiyi" is "refined". From the discussion here, we can clearly see the influence of Laozi. Lu's "Spring and Autumn Annals" holds that everything that comes from "essence" (Tao) is constantly moving, "changing with things, not ending in poverty". (Xiaxian) The sun, the moon and the stars in the sky and the spring water on the ground are constantly moving. "The sky is high and the sun, the moon and the stars never stop raining. The land is big, and the bare scales of spring grass never stop. "(Look at the watch) But it is worth noting that Lv Chunqiu regards the movement of matter as a cyclical process." When things move, they sprout; When they sprout, they grow, grow, grow; When they grow, they grow; When they grow up, they decline; When they decline, they kill; When they kill people, they hide; When they died, they were inspired. "("The Road to Love ")

In the view of social history, Lu Chunqiu thinks that history is constantly developing: "The present is the ancient, and the ancient is the later. What is today for future generations, and what is today for ancient times. Therefore, if you know today, you can know the ancient times, if you know the ancient times, you can know the past and present. " ("Long View") In other words, the development of history is a link, and people who look at today will still look at the present, and there is no such thing as the past. Understanding the past helps to understand today. However, understanding the past does not mean sticking to it. On the contrary, the times have changed, and the corresponding laws, regulations and policies have to be changed to meet the needs of the times: "If you can't, it will be chaotic, and if you obey the law, it will be contradictory; Rebellion can't protect the country. The world has changed, and it is appropriate to change the law ... so everything must be done according to law, and the reformers change with the times. " Two fables are also used to illustrate this truth: the Chu people waded into the river, and their swords fell into the water from the boat, saying, "It was my sword that fell." Stop the boat from where it has been signed and enter the water. The boat did it, but the sword couldn't. If you save the sword, it won't be chaotic! Jing people want to attack the song dynasty, so that people can show their water first. Those who drown are beneficial, and the Jing people know it. They follow the table and wade at night. More than 1000 people were drowned, and the army was surprised and bad. Both of these fables can be found in the Book of Tea. The former is the familiar "carving a boat for a sword". These two fables satirize the people who are stuck in the mud and don't know how to change, and also vividly show Lu's view of history in Spring and Autumn Annals.

Lv Chunqiu inherited Lao Zi and Zhuang Zi's thought of inaction, and advocated that the consolidation of political power lies in inaction, and that "there is a master of Tao, so don't do it" and "govern by inaction". ("knowledge"), only this kind of "inaction" and "virtual quietness" can achieve the free state of doing nothing and doing everything.

Lu's Spring and Autumn Annals also embodies some musical aesthetic thoughts. It links the production of music with everything in the universe, and puts forward that "born in the test, born in Taiyi" (Tai Yue), and discusses the psychological process of music production from the inductive relationship between "mind" and "thing". The concept of "fitness" is put forward, emphasizing the "fitness" of voice and the "fitness" of mind to obtain the feeling of beauty.
