Beginning of winter is one of the 24 solar terms of the Chinese nation. In ancient times, Li Si refers to the beginning of spring, summer, autumn and winter.

This day in beginning of winter indicates that winter is about to begin, which is the turning point of autumn and winter. This season is not only the division of autumn and winter seasons, but also a day to rest and treat yourself. Twenty-four solar terms say that "winter is the end, and everything is harvested." The crops in autumn are harvested and dried, and the animals in winter are hidden on the earth.
