To the extreme of emptiness, stay quiet and sincere. ——"Laozi" Chapter 16

Xu and Jing both describe a state of mind that is originally empty and peaceful, but becomes uneasy due to selfish desires and external interference. Therefore, Lao Tzu advises people not to strive for fame or selfish desires, but to let their minds return to their natural state and obey the laws of nature.

Laozi’s philosophy advocates that human power should not go against nature, and that no matter how we deal with people or govern the country, we must let nature take its course. This point runs through the whole book, such as,

Retreat after success, the way of heaven. ——Chapter 9 of "Laozi"

This is the natural law that tells people to limit their abilities in moderation. They cannot know how to advance and not know how to retreat, and they are good at fighting but not good at giving in. But it should be noted that "retirement" here does not mean that people should become hermits, but that people should not achieve success, not be self-aggrandizing, not controlling, not showing off their edge, and not being aggressive.

The people will not interact with each other until they grow old and die. ——"Laozi" Chapter 80

This is originally the embodiment of Laozi's political ideal of "a small country with few names". From it, we can also see Laozi's philosophy of life, which is to obey nature. He believed that at that time, a self-sufficient pastoral life was most in line with the laws of nature, so he painted a beautiful picture of every family enjoying themselves.
