Xunzi, whose name is Kuang and whose word is Qing, was a native of Zhao at the end of the Warring States Period (now Anze County, Shanxi Province). Xunzi lived between 298 and 238 BC. Xunzi gave lectures in the State of Qi and was recommended as the lecturer of Xuegong for three times. Later, he settled in Lanling, Chu, and wrote a book. He is the last master of Confucianism, and now he has 32 books of Xunzi, covering philosophy, politics, military affairs, ethics and health care. Xunzi thoroughly studied the thoughts of various schools since the Spring and Autumn Period and the Warring States Period. Through research, criticism and mastery, Xunzi really became a great thinker who "learned from the changes of ancient and modern times and became a unified statement", and opened a new generation of style of study, especially for Taoism and Legalism. Xunzi's thoughts on "man can conquer nature" and "control destiny and use it" shine with the light of materialism and illuminate the future generations.

Xunzi's health-preserving thought runs through his materialist dialectics of "man can conquer nature" and "control destiny and use it" Xunzi didn't generally talk about keeping in good health. Xunzi's discussion on the way of health preservation has a series of characteristics, such as "governing qi and nourishing the heart" and "being empty and quiet", "maximizing yin and yang" and "everything depends on life", "keeping abreast of the times" and "self-cultivation and self-improvement". "Xunzi's Persuasion" specifically discusses the strong will and perseverance of "perseverance, stone can be carved" in health preservation and monasticism. Xunzi is a representative of Confucianism who pays equal attention to both scholarship and enlightenment. He put forward the theory of learning from others in health preservation and monasticism.

Throughout history, Confucianism in China, from Confucius to Mencius and then to Xunzi, discussed the ways of keeping in good health in different historical periods. Confucius put forward "Benevolence leads to longevity", Mencius put forward "cultivating noble spirit", and Xunzi emphasized a series of ways of keeping in good health, such as "governing qi and nourishing heart" and "self-cultivation and self-improvement". Xunzi's theory of health preservation is more profound, concise and profound than Confucius and Mencius. To understand Xunzi's idea of keeping in good health, it is necessary to do in-depth research on Xunzi's works, and then to learn from them, so as to get the gist.

Xunzi's theory of keeping in good health covers a wide range, so we focus on three aspects. It is inevitable that the words of one family are biased, and they only seek to attract jade.
