Is spring cold a normal solar term?

Generally, in early spring, the temperature will start to rise, and then the winter wind will turn into the summer monsoon. At this time, the cold air from the northwest will invade our south, and the cold air from the north, south and south will meet with the warm and humid air from the south, and then it will form a continuous low temperature and rainy weather. At this time, the temperature will drop greatly. This is what people call cold spring, but spring should have been a long-term spring planting season.

However, spring is a pure season. Long rainy days will have a great impact on our agricultural production and life. The seeds planted by Yan Chungang will freeze to death alive, which will affect the harvest of our people for one year. Therefore, the people are very reluctant to have a cold spring. Therefore, after years of observation, they found a rule that there would be no late spring chill during their twelfth month in beginning of spring.

Therefore, as the saying goes, you don't know until you experience it. For example, the twelfth lunar month of the Year of the Dog is from1October 20 18 to 17 to February 14 of 20 18 in beginning of spring. According to our explanation of ripening, there should be no cold spring in 20 18 years, but it still happened in April of 20 18 years, so this sentence is not completely accurate. It may be related to the greenhouse effect in recent years and the appearance of some extreme weather. 20 19 The twelfth lunar month of the Year of the Pig is from February 26th to1October 24th, 2020, but what about it? It is said that the solar term in beginning of spring on February 4th is not in the twelfth lunar month, so it is likely that there will be a cold spring next year.

So, when the time comes, everyone can verify whether this proverb is reasonable. ?
