Is there a saying of eight styles in Neijing? What are the Eight Winds?

The movement of the sun and the moon not only forms the four seasons, but also leads to the climate change of wind, rain, cold and temperature. "Han Shi Tian Wen Zhi" says: "There is wind and rain in the month, and it is cold and warm in the day." It means that the movement of the moon leads to wind and rain, and the movement of the sun leads to changes in cold temperature. Wind plays a very important role in climate change, so both medicine and Yi pay attention to the role of eight winds. Neijing attaches great importance to the pathogenic factors of wind: "Wind is the source of all diseases." (Jade machine is really dirty) [1] "When evil wind comes, it is as sick as wind and rain" ("Yin and Yang should be alike") [1]? There is another cloud: "There are eight winds in the sky and five winds in the meridians ... Eight winds cause evil, thinking that the wind in the meridians touches the five internal organs and evil spirits come." (Jin Kui is embattled) [1]? However, the evil of the eight winds in Neijing has its regularity. "Eight Winds in the Nine Palaces of Lingshu" specifically discusses this law and gives a detailed description of the eight winds: "The wind comes from the south and is famous for being big but weak; ..... The wind is blowing from the southwest, called Moufeng; ..... The wind comes from the west and is called Feng Gang; ..... The wind blows from the northwest, which is called folding wind; ..... The wind comes from the north, which is called Dagang wind; ..... The wind blowing from the northeast is called fierce wind; ..... The wind from the east, a breeze; ..... The wind comes from the southeast wind, which is called weak wind. " The names of the eight winds in the Book of Changes are Feng (corresponding to the north position), Tiaofeng (corresponding to the northeast position), Mingfeng (corresponding to the east earthquake position), Qingming Wind (corresponding to the southeast position), Jingfeng (corresponding to the south position), Liangfeng (corresponding to the southwest position) and Hefeng (corresponding to the right position).

Although the names of the two sets of Eight Winds are different, their essence is the same, and they are all internally related to the theory of "Guaqi" in the Eight Diagrams, because the two sets of Eight Winds systems are related to the four seasons and eight seasons and the orientation of the Eight Diagrams the day after tomorrow. "White Tiger Shu Tong Zheng Ba Feng" has a cloud: "The wind is lovely, too. Success in raising a family is like gossip. " However, in 1977, "Taiyi Jiugong Zhanpan" unearthed from the tomb of Ruyin Hou in the Western Han Dynasty in Shuanggudui, Fuyang County, its "names of the nine palaces and the number of solar terms in each palace are completely consistent with the first picture of Lingshu Jiugong Eight Winds" [4]? It can be proved that the theory of Eight Diagrams "Guaqi" existed at least in the pre-Qin period, and it is intrinsically related to the theory of Eight Styles. The supplementary evidence is recorded in Historical Records: "Cool breeze is located in the southwest dimension, the main place". Because Kun is the land, the cool breeze has always been matched with the location of Southwest Kun here. Sima Qian's research on Yi can be traced back to Tian He in the early Han Dynasty. So the theory of "Guaqi" should have existed by this time, which further proves how correct Mr. Liu Dajun's assertion that "Guaqi existed before Qin Dynasty" is! Because it is not the focus of this article, I will not go into details here. ?

In Neijing, there is another person who is directly related to the theory of "Guaqi": "Spring should be mild, summer should be mild, autumn should be mild and winter should be mild. Therefore, on the forty-fifth day of winter solstice, the yang is slightly higher and the yin is slightly lower; On the 45th day of the summer solstice, the yin is slightly higher and the yang is slightly lower. Sometimes yin and yang are related to the pulse, and the period is lost. Knowing the pulse stage, you know life and death. " (On Meridian Pulse) [1]? According to Wei Xiang's so-called "winter and summer solstice, the order of the eight winds stands, and everything is natural, each has its own regular duties and is not related. Tai Hao, the God of the East, took advantage of the earthquake to cure the four springs; Emperor Yan, the southern god, rode away from Heng Sixia; Shao Hao, the God of the West, embraced autumn; Zhuan Xu, the god of the north, took advantage of the right to camp for the winter; Huang Di, the God of the Central Committee, brought Kun Gen down to earth (Han Wei Chuanqi) with the same purpose. ?

According to the different wind directions of different festivals, the Eight Winds can be divided into Zhen Feng and Virtual Wind: "Because the wind always occupies. The wind comes from the hometown where it lives. It is the real wind, the main destiny and the long-term cultivation of all things. Judging from its rushing wind, the injured are also the main killers and the main victims. " ("Nine Palace Eight Winds") [2]? Zhen Feng is a positive wind, while virtual wind is an evil wind. Therefore, we should "stay away from the empty wind." Therefore, saints should avoid virtual evil, such as avoiding arrows, and evil can harm them. " ("Nine Palace Eight Winds") [2]?

In the application of the eight winds theory and the eight diagrams theory, the difference between Yi and Yi lies in that the former focuses on the nature of heaven to establish human nature, while the latter focuses on the phenomenon of heaven to promote human physiology and pathology. First, the eight winds theory in Neijing is more detailed in the date division, except for dry (also known as Tianmen) and lost (also known as Earth Tiger). However, the eight winds of the Eight Diagrams and Qi in the Book of Changes are mainly 45 days, that is, 360 days. The former is closer to the actual number of one year old. ?

Second, there are different ways to wait for the weather. Neijing advocates that human diseases can be broken in eight days, saying that "there is rain first, then there is dryness." Zhang Jingyue notes the cloud: "The wind and rain come early, and it is full of gas, so it is rainy; The wind and rain came later, and its qi was insufficient, so it was dry. "But the eight diagrams in the Book of Changes are based on the date of the handover of the eight sections, and the qi will be released at the corresponding time. Such as "dry, northwest also, Lord beginning of winter, people, white gas out straight dry, this meaning also. Anger comes from the right, everything dies, anger comes from the left, and everything hurts. " (page 200) [5]? The rest of the hexagrams are analogized, and the rise and fall of qi depends on the arrival of qi in the morning and evening: qi is abundant if it does not arrive, and qi deficiency if it does not arrive, which further matches the deficiency of natural qi (weather) and the deficiency of human meridians.
