If "Bai Lu" is the transition from hot to cool, "Han Lu" is the transition from cool to cold. After the Cold Dew solar term, the days become shorter and the nights longer, the sunshine decreases, the heat slowly recedes, and the cold gradually sets in. The temperature difference between day and night is large, it is slightly chilly in the morning and evening, and the air is relatively drier.
After the Cold Dew, the temperature in most parts of southern my country continues to drop. The average daily temperature in South China is less than 20℃. Even in the coastal areas of the Yangtze River, the mercury column hardly rises above 30℃, while the lowest temperature can drop below 10℃ (due to global warming, the above average daily temperatures may deviate).
Except for a few river valley lowlands in the Northwestern Plateau, the average temperature over a five-day period is generally below 10°C. According to the climatological standard for dividing the four seasons, it is already winter. Thousands of miles of frost and tens of thousands of miles of snow are flying, which is completely different from the autumn scenery in the south.
