The moral of winter moon

Winter Moon is the November of the lunar calendar, also called Long Qian Yue and Long Moon. The arrival of the winter moon means that it has entered winter and the weather will gradually get cold. In ancient times, the winter solstice was the New Year, and the winter solstice was coming soon. Since then, the saying that "the solstice in winter is as big as a year" has been circulated among the people. With the change of the times, the solstice of winter has long been forgotten, and now the New Year is the first day of the first month.
