Having enough to eat and wear warm clothes, living in seclusion, without education, is close to an animal, that is to say, people have enough to eat and wear warm clothes and live comfortably, but without education, they are almost like animals. It shows that material civilization is not enough, and spiritual civilization education must keep up.

On Mencius and Teng Wengong, written by Mencius' disciples during the Warring States Period, said: "Those who gain the Tao are well fed, well clothed, and live in seclusion without teaching, which is close to animals."

Introduction of Mencius;

Mencius is a Confucian classic written by Mencius and his disciples Zhang Wan and Gongsun Chou in the middle of the Warring States Period. It was first seen in Zhao Qi's inscription "Mencius": "This book was also written by Mencius, so it is called Mencius". Mencius was listed as "Four Books" by Zhu in the Southern Song Dynasty (the other three books were Daxue, The Doctrine of the Mean and The Analects of Confucius).

There are eleven pieces of Mencius recorded in History of Han, and there are seven pieces and fourteen volumes. The total number of words is more than 35 thousand words and 260 chapters. According to legend, there are four other books of Mencius, which have been lost (this book of Mencius is a fake of Yao Shizhen in the Ming Dynasty). This book records the politics, education, philosophy, ethical thoughts and political activities of Mencius and his disciples. There are four books and five classics in ancient examinations.
