Mencius (372- 289 BC) was born in Zou (now Zoucheng, Shandong) and was a disciple of Confucius' grandson. China, a thinker, educator, essayist and politician in the Warring States period in ancient times, is one of the famous representatives of Confucianism.

Mencius' ancestors were aristocrats in the state of Lu, and later his family declined and moved from the state of Lu to Zou (now southeast of Zoucheng, Shandong). He lost his father when he was three years old, and Meng Mu brought him up. When Mencius was a child, his mother moved three times to give him a good learning environment. Later, people called it the Three Major Movements in Meng Mu. Meng Mu's godson is very strict, and his "moving godson" and "broken loom" have become a beautiful talk throughout the ages. There is a saying in Saint Amethyst that "Meng Mu used to choose a neighbor".

Mencius lived in an era when a hundred schools of thought contended, and "Yang Zhu's words prevailed in the world". Mencius criticized it fiercely from the standpoint of Confucianism. Mencius inherited and developed Confucius' thoughts and put forward a complete ideological system.

Mencius traveled around Qi, Jin, Song, Xue, Lu, Teng and Liang countries to lobby his thoughts of "benevolent governance" and "kingliness". However, because the vassal states were busy with war at that time, his theory of benevolent governance was considered as "circuitous and wider than things", and almost no one adopted his thought of governing the country. He returned to China to give lectures and write books with his disciples, and wrote seven "Mencius". Mencius maintained and developed Confucianism, put forward the theory of "benevolent governance" and "good nature" and adhered to "people-oriented".

His thoughts have a great influence on later generations. But his position was not very high before the Song Dynasty. Since Han Yu listed Mencius as the only person in pre-Qin Confucianism who inherited Confucius' "orthodoxy" in The Original Road, there has been a "promotion movement" of Mencius, and his status has gradually improved. His theory had a great influence on the Song Dynasty. In the fourth year of Xining in northern Song Shenzong (107 1), Mencius was listed as one of the subjects in the imperial examination for the first time, and later it was promoted to a Confucian classic. Zhu in the Southern Song Dynasty combined it with The Analects of Confucius, Daxue and The Doctrine of the Mean into four books. From the Yuan Dynasty to the first year of Shun Dynasty (1330), Mencius was named "Yashenggong" and later called "Yashenggong", ranking second only to Confucius. His thoughts and Confucius' thoughts are collectively called "The Way of Confucius and Mencius".
