Mencius is a household name in China. Together with Confucius, the founder of Confucianism, he was called "Confucius and Mencius" and himself was called "Yasheng". Mencius' name was Ke, and when his distant ancestor was a noble of Lu. Later, his family declined and moved from Shandong to Zou (now southeast of Zoucheng, Shandong Province). He lost his father when he was three years old, and Meng Mu brought him up. When Mencius was young, his mother found three places to give him a good study environment, which was later called "Three Movements to Meng Mu". Meng Mu's godson is very strict, and his "godson moving the earth" and "broken loom" have become a beautiful talk throughout the ages. When Mencius grew up and learned, he lobbied the princes. It is reported that everywhere he went, princes and nobles held grand banquets. His disciples didn't understand this, suspecting that it didn't conform to the Confucian spirit of "a gentleman doesn't talk about profit". Mencius took it lightly. He explained: "If it's not a way, you can't give it to others." In that way, it will be accepted by the world, not by the Thai people. "In other words, the key to the problem is to see if it is against morality, and it is not too profitable; No way, no matter how small the profit is, you can't stand it. What Mencius objected to was that everyone put "benevolence and righteousness" behind their heads, focused on "profit", and opposed "profit without justice" and "benefit before justice". Mencius later retired to give lectures, and together with his students, he "wrote a book with preface poems, described the meaning of Zhong Ni, and wrote seven pieces of Mencius".

Mencius lived in the Warring States period, competing with each other and fighting among princes. Although he has lofty aspirations and eloquence, such as "being honest, putting aside heresies, staying away from evil things and releasing obscene words" and "who should fall behind in today's world", his theory of "benevolent governance" is out of touch with current events and has repeatedly hit a wall in the political arena, but it is precisely this that makes him succeed in the theoretical arena of life. He held high the ideal of personality, praised the independence and initiative of individual values, and discussed the methods of life cultivation and how to reach the ontological realm on the road of life, which had a far-reaching impact on later generations. Comrade Mao Zedong embellished it with a sentence from Mencius Teng Wengong: "The husband moistens it, and it lies with the monarch, the minister and the son." The meanings of "Zedong" and "Runzhi" complement each other. He often quotes the chapter "God's great responsibility to the Sri Lankan people" to encourage and spur himself, exercise his physique and sharpen his character and fighting spirit. In his works, he quoted Mencius' famous sayings, such as "There is no righteous war in the Spring and Autumn Period", "If you don't do it, you can do it", "If you are faint, you can shine" and "If you have the heart, you can think" to explain the basic principles of Marxism and the line and policy of revolutionary struggle.

Among Mencius' life theory, the most distinctive one is his theory of nourishing qi, that is, the so-called "I am good at nourishing my noble spirit". What he called "aristocratic spirit" has two characteristics: "supreme" and "supreme". "Maximum" is the transcendence of individual smallness; "Supreme rigidity" is a transcendence of individual cowardice. In Mencius' view, "everyone can think of Yao and Shun", and individuals can become saints like Yao and Shun through their own conscious efforts. This "supreme" lofty spirit is not the product of subjective imagination, but the sublimation of personality obtained from practice. He asked people to "work hard on their minds and bones", "be worthy of the sky, not be human", "wealth can't be lewd, poverty can't be moved, and the powerful can't be bent". In fact, Mencius' lofty spirit is a high spiritual realm and a profound reflection on China's human spiritual life. The philosopher Feng Youlan once said, "In any case, the word' sincerity' is still a common word, which is a word in China culture. Only by understanding this vocabulary can we understand China culture and the spirit of the Chinese nation. "

At the end of the Southern Song Dynasty, the national hero Wen Tianxiang was captured after failing to resist the Yuan Dynasty. He sternly rejected the threats and inducements of the rulers of the Yuan Dynasty, and wrote an impassioned and immortal Song Zhengqi in prison: "Magnificent and awe-inspiring. When it runs through the sun and the moon, life and death are at peace. The earth depends on it, and the Tianzhu depends on it. The three cardinal principles are life and morality is the root. " Perhaps this is the best annotation to the sentence "I am good at cultivating my noble spirit"
