CCTV News: During the Qingming Festival, the grass and trees are green, the weather is clear and bright, and everything is thriving. "Qingming" is not only one of the twenty-four solar terms of the lunar calendar, but also a traditional festival that has been continued for thousands of years in my country. Qingming is also closely related to agricultural activities. There are also folk sayings about early Qingming, late Qingming, first Qingming, and later Qingming. According to meteorological experts, this year's Qingming Festival is a situation of "post-Qingming Festival".

The Qingming solar term is an important node for the full development of agricultural activities after the winter break. In "Autumn Night in Chang'an", the Tang Dynasty poet Zhang Xiaobiao wrote: "The calf blooms in spring, and the children wait for warm farming." This depicts the increasingly busy farming scene of the fields from Qingming Festival to Grain Rain. This is not only conducive to the sowing of grain crops, but also a good time for planting melons, beans, cotton and forests. Around the Qingming Festival, people acted in time and were busy farming, fertilizing, weeding and irrigating in the fields.

Before Qingming and after Qingming, it is closely related to spring plowing and sowing

Many folk farming proverbs are also related to Qingming farming, such as "February Qingming is warm, and the cattle are frozen to death in Qingming is cold in Qingming is not before, and March is not after." Therefore, there are differences between the people's Qingming Festival in the front and Qingming Festival in the back.

Wang Chunzhi, a senior engineer at the National Meteorological Center, introduced that Qingming Festival in the first and Qingming Festival in the later period are actually agricultural proverbs for spring plowing and sowing, which is closely related to farming. This year is the situation of "post-Qingming" and this is closely related to the appearance of the Qingming solar term in February and March of the lunar calendar. It usually occurs in the second month of the lunar calendar, when the cold and cold air in the north and south frequently meet, the temperature is unstable, and the possibility of "late spring cold" is more likely to occur. However, if the Qingming Festival occurs in the third month of the lunar calendar, you must hurry up and not postpone it anymore. Therefore, around Qingming Festival is a critical period for spring plowing and sowing.

In the early Qingming Festival, warm and late Qingming Festival, cold. This year is late Qingming Festival.

In addition to "before and after", there is also a saying of "morning and evening" in Qingming Festival, which is determined based on the time of the Qingming Festival. If the time of the Qingming Festival is in the morning, the weather will be particularly warm after the Qingming Festival; if it is in the afternoon or evening, it may be cold for a while after the Qingming Festival. As the saying goes, "Early Qingming is warm; late Qingming is cold." At 20:49 on April 4 this year, the Qingming Festival officially entered, which is "Evening Qingming Festival". Therefore, it may be cold for a while after Qingming Festival, so we need to be careful of the "late spring cold".
