1. In metaphysics, there is nothing taboo in the five days of severe cold. In the folk, it is a taboo not to snow in the cold weather. There is a saying that "it is good to have a good year in the cold day", which means that it is auspicious to snow in the cold weather, which makes sense from the perspective of natural science.

(2) The custom of severe cold solar terms: the severe cold solar terms coincide with the end of the year. In the severe cold solar terms, people should not only conform to the solar terms, but also be busy with farming, preparing for the New Year, catching up with the new year's goods, posting Spring Festival couplets, sweeping away dust and things, removing old cloth and making new ones, preparing various sacrificial articles, curing bacon and sausages, cooking chickens, ducks and fish, etc., as well as offering sacrifices to ancestors and various gods.

(3) Pay attention to the solar term diet in the great cold: Great cold and beginning of spring should be handed over and adapt to the seasonal changes. In the severe cold, people should gradually reduce their food intake and eat more foods with ascending and dispersing properties in order to conform to the rising trend of everything.

Winter, as the last solar term, mainly supplements the spleen, and health care needs to pay attention to replenishing the spleen.

(4) Prevention of diseases in severe cold season: Cardiovascular and cerebrovascular diseases, emphysema, chronic bronchitis, cardiovascular and cerebrovascular diseases and respiratory diseases are the most in need of prevention in severe cold season.

You need to wear a coat, a mask, a hat and a scarf when you go out.
