What is the symbol of winter?

Chimonanthus praecox, frost flower, rime, ice sculpture, snowflake, etc. In northern China, snow is an important symbol of winter. In the middle and lower reaches of the Yellow River in northern China and its vicinity, the snow in winter is often not as big as the light snow solar terms. The main reason is that the light snow solar term is ahead, the temperature is high, the total amount of water vapor in the air is larger than that of heavy snow solar term, and the possibility of heavy snow is greater.

The things that symbolize winter are wintersweet, frosted flowers, rime, ice sculptures, snowflakes and so on. Winter is one of the four seasons, which traditionally begins with "beginning of winter" among the 24 solar terms. In winter, life is closed and everything enters a state of recuperation. In winter, that is, "everything will be harvested in the end", after beginning of winter, everything began to be hidden. Li Si's division of four seasons reflects many characteristics such as climate and phenology. At present, four seasons are often divided according to the temperature change, and the method of "weather average temperature" proposed by modern scholar Zhang Baokun is adopted. According to the four seasons divided by the weather average temperature method, the average daily temperature is equal to or lower than 10 degrees Celsius for five consecutive days, which is regarded as entering winter.

In northern China, snow is an important symbol of winter. In the middle and lower reaches of the Yellow River in northern China and its vicinity, the snow in winter is often not as big as the light snow solar terms. The main reason is that the light snow solar term is ahead, the temperature is high, the total amount of water vapor in the air is larger than that of heavy snow solar term, and the possibility of heavy snow is greater. In fact, the solar term with the heaviest snow in the middle and lower reaches of the Yellow River and its vicinity is neither "light snow and heavy snow" nor "slight cold and severe cold" (because the temperature was low at that time and there was less water vapor in the atmosphere), but a rainy solar term in spring.
