Who wrote the article "Yu Gong Yi Shan"?

There are two big mountains in front of Gong Yu's house, and he is determined to level them. Another "smart" wise old man laughed at him for being too stupid and thought he was no good. Gong Yu said, "I had a son when I died, and my son had a grandson when I died. There are endless descendants, and the two mountains will eventually be leveled. " Later, moved by the Emperor of Heaven, the Emperor of Heaven ordered Hercules to move the two mountains. Metaphor means that you can succeed as long as you have perseverance.

Yugong Yishan is one of the ancient Han folklore in China, which is selected from Liezi Tang Wen. According to legend, the author is Lieyukou. Lieyukou, also known as Yukou (also known as "Yong Kou" and "Guo Kou"), is said to be a Taoist and a Zheng native in the early Warring States period, contemporary with Zheng Miaogong. His knowledge originated from the Yellow Emperor Laozi, and he advocated to wait and see. At the end of the Han Dynasty, there were eight volumes of Liezi in the "Daoism" section of Ban Gu's Records of Literature and Art, which had long been lost.

About the author: Liezi was born in Putian (now Zhengzhou City, Henan Province) during the Warring States Period. A famous representative of Taoist school, a famous thinker, fable and writer. It has a far-reaching influence on philosophy, literature, science and technology and religion of later generations. The author of Liezi. At that time, because people used to add a word "Zi" after the surname of a learned person to show respect, Lieyukou was also called "Liezi". The theories of "celestial body movement", "earth movement" and "infinite universe" in Liezi are far earlier than similar theories in the West. During the Tianbao period, Emperor Xuanzong of the Tang Dynasty named Liezi "Xu Chong Real Person". Liezi was poor all his life, did not seek fame and fortune, did not enter the officialdom, lived in seclusion for 40 years, and devoted himself to writing 20 articles, about100000 words. There is a Liezi that has been handed down to this day. Liezi was studied in the pre-Qin period, and it was still popular in the Western Han Dynasty. The Western Jin Dynasty was troubled by Yongjia Rebellion and was mutilated after crossing the river. Later, it was completed in Zhangzhan. There are eight existing articles: Tian Rui, Huangdi, Zhou Muwang, Zhong Ni, Tang Wen, Li Ming, Yang Zhu and Fu Shuo. Among them, fables such as "A Mountain of Yugong", "Worrying Worryingly", "Two Children Arguing in the Sun", "Snow Club in Chicken Farm" and "Tang Wen" are well-known and widely circulated. Among them, "The Day of Two Children Debate" was included in the sixth volume 1 text of the primary school Chinese People's Education Edition. Liezi has always kept a low profile, and there is a saying that "Liezi lived in Zhengpu for forty years without knowing it". It can be seen that he really reached the realm of "harmony but difference" that Laozi said, so Liezi's deeds in history are also very few.
