1. In the north, regardless of the rich or the poor, jiaozi is an essential holiday feast during the winter solstice of the Lunar New Year. There is a saying: "On October 1st, the solstice of winter comes, and every household eats jiaozi." A bowl of hot jiaozi brings not only food and clothing in winter, but also warm wishes and sustenance to the family. This custom was left in memory of Zhang Zhongjing, a "medical sage", who gave up medicine from the winter solstice. When you eat jiaozi on the solstice in winter, you will never forget the kindness of Zhang Zhongjing, a "medical sage", in "Quhan Joule Decoction".
Many areas have the custom of offering sacrifices to heaven and ancestors from the winter solstice, and some places still celebrate this festival from the winter solstice. Every family provides genealogy, ancestor statues, memorial tablets, etc. In the upper hall of the home, an altar, incense burners and offerings are placed. In some places, while offering sacrifices to ancestors, they also offer sacrifices to gods, land gods and deities, so as to make the next year's weather favorable and the family prosperous.
