The beginning of winter is the nineteenth of the twenty-four solar terms and the beginning of winter. The handle of the bucket points to the northwest, the ecliptic longitude of the sun reaches 225°, and it meets between November 7-8 of the Gregorian calendar every year. The establishment is the beginning of the establishment; the winter is the end, and all things are collected. The beginning of winter means that anger begins to accumulate, and all things enter a state of recuperation and collection. Its climate also transitions from a dry and rainy autumn to a rainy and cold winter.
