Yang Zhu, a philosopher in the pre-Qin period, was a native of Wei State (now Kaifeng City, Henan Province) in the Warring States Period. Born and bred, he opposed the universal love of Confucianism and Mohism, especially Mohism, advocated valuing life and oneself, attached importance to the preservation of personal life, and opposed others' encroachment on himself and others. His dissolution can be found in Zhuangzi, Mencius, Han Feizi and Lv Chunqiu.

On one occasion, Mozi's student Bird Slip asked Yang Zhu, "If pulling out a hair on your body can benefit the whole world, will you?" "The world's problems can never be solved by pulling out a hair!" Yang Zhu replied. The bird asked again, "If you can, will you?" Yang did not answer.

A dime is good for the world, not for nothing.

The great wisdom contained here asks how many people in the world can understand it. Doing nothing and wandering around exist in theory, but Yang Zhu has his own way, which is despised by the world. Yang Zhu's heyday was earlier, but no one questioned it. Prove that most people agreed with this view at that time. Yang Zhu.

Pull out a hair? Why don't you pull it out? What's the use of pulling out meaningless things This sentence has no dialectical relationship. If we can get it dialectically, why bother in the world? Everything can only be understood in life. Some people accidentally understand that great wisdom cannot be recorded in words, not because they don't want to, but because they can't express it. I think Yang Zhu also has unspeakable pain.
