The origins and customs of the Dahan solar term are as follows:

1. Origin

Dahan is the last solar term among the twenty-four solar terms. The sun falls around January 20 every year. When it reaches 300 celestial longitude, it is called "Great Cold". Dahan means that the weather is extremely cold. Cold waves frequently move southward during the Great Cold, which is a cold period of the year in most parts of my country. The wind is strong, the low temperature is low, and the snow on the ground does not melt, presenting a severe cold scene of ice and snow, and freezing temperatures.

During the Great Cold, the atmospheric circulation is relatively stable, and the circulation adjustment period is about 20 days. When this kind of circulation adjusts, large-scale rain, snow, and windy cooling often occur.

2. Customs

According to the customs of our country, especially in rural areas, every time during the Great Winter Festival, people are already busy removing old cloth, making new dishes, pickling new year dishes, and preparing new year goods. . During the period from the Great Cold to the Beginning of Spring, there are many important folk customs, such as the Wei Ya Festival. The Dahan solar term is full of joy and joy, and it is a cheerful and relaxing solar term.

Tail teeth originate from the custom of worshiping the Lord of the Land to get teeth done. On this day, traders will hold a banquet, and white-cut chicken is an indispensable dish at the banquet. There is a rumor that whoever the chicken heads towards means that the boss will fire him next year. So now some bosses usually turn the chicken head toward themselves so that their employees can enjoy the meal with peace of mind and have a peaceful New Year when they go home. In winter, Nanjing people like to stew and drink soup. The Great Cold is around April 9th. The traditional custom of eating one chicken in 1999 is still respected by many citizen families. Most Nanjing people choose old hens. Drinking chicken soup in the cold winter is such a treat.

In the Great Cold solar term, you need to go to bed early and get up late

In the Great Cold solar term, everyone needs to pay attention to the fact that you must go to bed early and get up late, because the "Great Cold" is the end of winter. As a solar term, in daily life, we should still adapt to the characteristics of winter's confinement, so we should go to bed early and get up late. Going to bed early is to nourish the body's yang energy, and getting up late is to nourish the yin energy. Therefore, during the Great Cold season, you need to go to bed early and get up late.
