What changes have taken place in the cold dew solar terms and why?

As the saying goes, "White dew does not show the body, cold dew does not show the feet." This proverb reminds everyone that once the Millennium solar term is over, you can no longer go shirtless when you wear clothes; After the cold dew solar term, you should pay attention to keep your feet warm.

Because autumn and winter alternate seasons, it is very important for health to reasonably arrange food, clothing, housing and transportation in autumn and adapt to climate change as much as possible.

Hope to give praise!
