Cheng Yuan is one of the representatives of the ancient Neo-Confucianism in China, and has made outstanding contributions in the fields of philosophy, education and morality. He believes that human beings should pursue knowledge and combine knowledge with practice. He advocates "seeking knowledge from things, seeking truth, seeking truth, seeking perfection and seeking essence". Cheng Yuan's thought has a far-reaching influence on later generations. He made great contributions not only to China culture, but also to the world culture.
The theory put forward by Cheng Yuan takes the human mind as the research core and emphasizes the consistency between behavior and thought, which is known as the originator of "Mind Learning". He believes that a person's mind should remain pure, which must be achieved through introspection and self-discipline. Today, his theory is regarded as a useful guide, which provides valuable philosophical thoughts for people to purify their minds and establish sound moral concepts, and has important practical significance.
