Traditional Chinese Medicine divides a day into twelve hours, represented by the twelve Earthly Branches and the theory of meridian flow and injection. The theory of Zi Wu Liu Zhu is a major component of traditional Chinese medicine, which studies the timetable of the circulation of qi and blood in the human body. Traditional Chinese Medicine believes that nature and humans are a unified whole, and the annual, seasonal, daily, and hourly cycles in nature affect the corresponding physiological and pathological cycles of people, such as pulse, spring string, summer flood, autumn hair, and winter stone; The changes in a person's condition are mostly mild in the morning, severe at noon, and even more severe at night. These situations are related to the circulation of qi and blood in the human body, that is, at different times, qi and blood flow to different meridians, which has a direct impact on the physiology and pathology of the human body, just like the biological clock effect proposed by modern science. The theory of Zi Wu Liu Zhu holds that the circulation of qi and blood in the human body follows a certain time without any reason, forming a large circulation channel. The connection sequence of the twelve meridians is as follows:
