What does it mean that early winter is light and cold, and yellow leaves fall?

Early winter is light and cold, and early winter leaves fall. It's a little cold, and the yellow leaves slowly fall from the trees, which means that the cold winter is coming again. It is difficult to appear in the south with four distinct seasons. Sometimes the temperature in winter will be so high that people want to wear short sleeves to go out.

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.

Li Si's division of four seasons reflects many characteristics such as climate and phenology. The 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. In 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.
