Confucius asked for gifts.
Confucius once asked him for a gift, then retired and wrote Laozi. When I say Lao Tzu, I mean Tai Shiyun or Lao Laizi. Whether Laozi was written by Laozi has always been controversial. Laozi used Tao to explain the evolution of all things in the universe, thinking that "Tao gives birth to one, two, two, three and three things" and "Tao" is "the fate of a husband is natural", so "man should be in the earth, the earth should be in the sky, the sky should be in the Tao, and the Tao should be natural". "Tao" is an objective natural law, and at the same time it has the eternal significance of "being independent and unchanging, walking without danger" The book Laozi contains many simple dialectical views, such as that everything has two sides, and the "movement of Tao" can be transformed from opposition, "the right is strange, the good is evil" and "the disaster is a blessing, and the disaster is hidden". He also believes that everything in the world is the unity of "being" and "nothing", and "being and nothing" are the foundation, and "everything in the world is born of something and born of nothing". "The way of heaven, the loss is more than enough, but the way of man is not, and the loss is not enough"; "People's hunger is as much as food tax"; "People die lightly, but they live on it"; "People are not afraid of death. Why are you afraid of death?" . His theory has a far-reaching influence on the development of China's philosophy, and its contents are mainly found in Laozi.
It's all polite. That's at least Confucius' elder.
