Mencius' famous words are included in Mencius, which is magnificent, full of emotion, eloquent and infectious, and has been passed down to future generations with far-reaching influence, becoming one of the classic works of Confucianism.
The work mainly records the thinker Mencius' thoughts on governing the country and his political strategy. It emphasized the importance of people, and took the lead in putting forward the idea that "the people are more valuable than the monarch", and the core of the idea is the word "mind". To put it simply, if you cultivate your own mind, you can influence the world from the inside out. The so-called "sage inside and king outside" means this, which has a profound influence on the later Neo-Confucianism of Cheng Zhu and Yangming's Mind.

Comparison between Mencius and Confucius:
Zhao Qi compared Mencius with the Analects of Confucius in the Inscription of Mencius, and thought that Mencius was "made to be holy". Therefore, although the History of Literature and Art of Han Dynasty only regards Mencius as a sub-book, it has actually been regarded as a "biography" book to assist the "classics" in the minds of Han people.
Emperor Wen of the Han Dynasty assigned doctors to The Analects of Confucius, The Book of Filial Piety, Mencius and Er Ya, which were called "Biographical Doctors". By the end of the Five Dynasties, Meng Chang, the master of the post-Shu Dynasty, ordered people to carve stones on eleven classics, including Mencius, which may be the beginning of Mencius' inclusion in the "Classics". Later, Song Taizong reprinted the Eleven Classics.
By the time of filial piety in the Southern Song Dynasty, the Four Books compiled by Zhu Xi were included in Mencius, which formally raised Mencius to a very high position. After the Yuan and Ming Dynasties, it became the content of imperial examinations, and it was also a must-read book for scholars.
