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 the 24 solar terms "beginning of winter" as beginning of winter. In winter, life is closed and everything enters a state of recuperation.

The commonly used methods of season division mainly include "solar terms method" and "temperature method". The winter divided by solar terms method starts from "beginning of winter" and ends before the next "beginning of spring". According to the temperature method, winter begins when the daily average temperature is lower than 10℃ for five consecutive days, and ends when the daily average temperature rises above 10℃ for five consecutive days.

Division of four seasons

The commonly used methods of season division mainly include "solar terms method" and "temperature method". The traditional division of the four seasons in China is based on the "four stands" among the 24 solar terms as the beginning of the four seasons. The change of the four seasons is a continuous process, and it is also a process of yin and yang transformation, and quantitative change produces qualitative change. In this gradual process, beginning of spring, Changxia, beginning of autumn and beginning of winter, also known as "Sili", are the opening of the season.

Traditionally, winter begins at the beginning of winter and ends in the next beginning of spring. Zhang Baokun, a modern scholar, put forward a new seasonal standard-temperature method, that is, the average temperature (the average temperature for five consecutive days) fell steadily below 10℃ in beginning of winter, rose above 22℃ in long summer, and rose below 10℃ in beginning of spring.

The seasonal method used in climatology is an improved version of Zhang Baokun's temperature method, which changes the "average temperature for five consecutive days" to "average temperature for five sliding days", thus enhancing the accuracy of seasonal division. However, no matter how scientifically defined, people always think that "beginning of winter" is the beginning of winter.
