There is a folk saying that "spring covers the autumn". What is the reason?

To cover spring and freeze autumn is to advise people not to take off their cotton-padded clothes in a hurry when spring comes, and not to wear too much when autumn is cold. Proper covering and freezing are good for your health.

Spring is because we all know that the temperature changes very quickly in spring, and we may be able to wear skirts barefoot the day before. I want to wear cotton trousers today. There are often cold air and cold currents in spring, so the temperature changes so quickly. Proper mulching can enhance the ability to resist cold and adapt to the changeable weather in spring.

Autumn freezing means that the weather is crisp in autumn and the temperature has just turned cold. It is not advisable to add clothes too early at this time. We should properly exercise our cold tolerance and be able to better cope with the coming winter. The human body has certain adaptability. If they are warm from the beginning, there may be no way to stop the cold when winter comes.
