It means that since there is nothing we can do about it, we should accept it as if it were fate. It means facing the helplessness and cruelty of reality with a peaceful mind.

Do what you know you can't do, but if you do it, you will be safe-the language comes from Zhuangzi.

Original text: "Zhuangzi on Earth": "It is extremely virtuous to know that it cannot but be prepared for danger in times of peace." Of people's misfortunes, they are predestined, so they accept them gladly.

Zhuangzi (about 369-286 BC), a philosopher in the mid-Warring States period, was born in Zhuang's family, Zhou's name, Zi Xiu (Zuo), Han nationality, and Meng (now Mengcheng, Anhui, also known as Shangqiu, Henan and Dongming, Shandong). He was a great thinker, philosopher and writer in the pre-Qin period of China.

Zhuangzi's imagination is extremely rich, his language is freely used and flexible, and he can make some subtle and unspeakable philosophies fascinating. His works are called "literary philosophy, philosophical literature". It is said that he lived in seclusion in Nanhua Mountain, so at the beginning of Tianbao, Emperor Xuanzong of the Tang Dynasty, he named Zhuang Zhou as the South China Reality and his book Zhuangzi as the South China True Classic.
