The normal wind of nature is different from the evil wind and the thief's abuse wind. The normal wind in nature is not only warm, gentle, soft and refreshing, but also has distinct seasonal characteristics and wind direction corresponding to the four seasons. Its seasonal characteristics are mainly as follows: warmer, hotter, wetter, drier autumn wind and cooler winter wind. Its wind direction has its regularity in different sections. The ancients called it "Shunling", which matches the Eight Diagrams and Nine Palaces. The specific wind directions are as follows: from beginning of spring (Gengen, tomorrow's sixth house), from the beginning of the day, it will be northeast wind in turn; The vernal equinox (earthquake, the famous Cangmen Palace) starts from the east wind; Changxia (A Xun, whose name is Gong) starts from the southeast wind. The south wind is an order from the day of summer solstice (belonging to the heavenly palace); Beginning of autumn (Kun, Xuanwei Palace) will be ordered by the southwest wind from one day; The autumnal equinox (right, Ming Cang Guo Gong) begins with the west wind as the order; Beginning of winter (a dry place called Silla Palace) had a northwest wind one day; From the day of winter (belonging to Han Shu, a famous leaf), the north wind is the order. After the wind of obeying orders hits people, it makes people feel refreshed, dispels worries and becomes addicted. On the contrary, it is a rebellious wind that blows people. In a word, any wind that is contrary to the above-mentioned normal natural wind characteristics, characteristics and wind direction belongs to the category of unhealthy wind, such as virtual evil and thief abuse, which are harmful wind and poisonous gas and are easy to get sick when blown on people. If common cold enters the body along the meridians, it will accumulate in the body. In the future, it will be called "the evil of traditional Chinese medicine" because of the heavy feeling of cold, heat, dampness, hunger and fatigue at the inner edge and the internal and external factors.
There are many manifestations of the wind of virtual evil and thief abuse, and the virtual one is called untrue. Sometimes, although the wind is not very strong, it feels chilly, or it is poisonous and foggy, or it is out of season, so people who are weak and sick are easily hurt by it. Evil is an incorrect statement. Anti-seasonal winds and winds that are not warm in spring, not hot in summer, not wet in long summer, not dry in autumn and not cool in winter are evil winds, which are easy to hurt people. Therefore, Neijing warns people to "avoid evil spirits". Thieves belong to the meaning of stealing in, in windy places, cold and humid houses, cracks in doors and windows, or naked clothes. Often attacked by thieves. The ancients said, "If you are not afraid of strong winds, you are afraid of thieves." That's the reason. Abuse of violence, strong winds, squalls, cyclones, sandstorms, stormy weather and other bad weather directly and seriously hurt people. Sometimes the wind of empty evil thieves' abuse comes, which hurts people especially. So whenever there is unhealthy weather, you must avoid it, which is not suitable for practicing outside. We also need to try to avoid the invasion of unhealthy trends in our daily life.
The purpose of practicing acrobatics is to get rid of illness and strengthen the body, prolong life and avoid the attack of cold to the maximum extent. Therefore, when exercising outdoors, you should choose a place with sunny weather, moderate temperature, mild breeze and suitable wind direction, which is called "the sum of heaven and earth, from all directions" and "the rise and fall of everything at the door of growth" in Neijing. Don't practice in an environment with the wind of virtual evil and the wind of thief abuse. If you practice indoors, the temperature difference between indoor and outdoor should not be too big, especially in hot summer and cold winter. If physical conditions permit, try to adapt yourself to the natural environment, which is conducive to maintaining good health. Therefore, Neijing advocates that "it is good for a wise man to be in good health, to be suitable for cold and summer, to be harmonious with each other, and to be both rigid and soft." If so, he will not do evil and live a long life. " We should not only adapt to the natural environment when practicing martial arts and avoid the attack of colds, but also pay attention to avoiding the harm of evil wind and poisonous gas in daily life to keep our health.
