Winter generally refers to winter. Winter is one of the four seasons. The change of seasons throughout the year is a continuous process, and it is also a process of yin and yang transformation, from one to two, from quantitative change to qualitative change. In this gradual process, beginning of spring, Changxia, beginning of autumn and beginning of winter, also known as Sili, are the beginning of the season. Traditionally, China regards beginning of winter as beginning of winter in 24 solar terms.
