The winter is the nineteenth of the twenty-fourth chronology, determined on the basis of the arrival of the sun at 225 degrees yellow. Winter is officially coming after winter. The grass and the trees are falling apart and the worms are sleeping, and all activities tend to stop. The winter is celebrated on 7 or 8 November each year, not only as the time of the harvest festival and the festival, but also as the season of the cold wind. There are customary activities such as October, Qin's first year, Cold Clothes Festival and Harvest Festival. At this time, in the north, it is the winter month of Meng, which is “water frozen and frozen”, and in the south, it is the day of light。
