Winter in Handan is one of the solar terms on the solstice.

The winter solstice is one of the 24 solar terms, which refers to the day when the sun runs to the tropic of Capricorn. It is the shortest day in the northern hemisphere, so there is a saying that the day becomes longer after eating the winter solstice meal. The winter solstice is the most important solar term in ancient times and the beginning of a year. As the saying goes, in winter, there is a tradition of ancestor worship in Jiangnan.
