As the saying goes, it's the Dragon Boat Festival, not the ghost in July and a half. Why am I afraid of rain on Dragon Boat Festival?

This kind of prediction from the people acts on agriculture. In the past, judging the weather was based on experience accumulation, unlike scientific and technological observation now. Therefore, in the past, we were not completely sure about the weather changes. We can only say that by summing up experience and accumulating from some phenomena, we will get some laws of the weather changing with time from these phenomena. Of course, the accuracy of these laws is actually half-open.

May of the lunar calendar is actually the beginning of the rainy season, which means that the rainy season in the subtropical temperate zone of the northern hemisphere begins in May, with huge rainfall and extreme weather, and the beginning of May means the beginning of the real summer. Summer indicates the hottest time, and the Dragon Boat Festival, as the real beginning of summer, has also become the beginning of the whole May.

The ancients were prone to accidents in hot and humid climate because of underdeveloped medical care and productivity. For agriculture, the rain in the first half of the year was too concentrated and prone to floods, but it may affect the rain in the second half of the year. That is to say, if there is too much rain in May, drought will occur in the second half of the year.

Dragon Boat Festival belongs to the beginning of May, which should be the representative of heat, but once it rains, the ancients will think it is unlucky, resulting in serious floods in the first half of the year. In fact, they just put in some guesses and predictions. At noon on the Dragon Boat Festival, it represents high temperature and summer heat, and rain represents humidity and coolness. The ancients thought it would collide, so they thought it would rain badly on the Dragon Boat Festival, which would affect the climate for a year, so everyone was afraid.

Of course, these experiences are also unreliable, because the ancients lived by the sky and put a lot of things into it with their own wishes. Because the ancients pursued the unity of heaven and man, they were very concerned about unusual phenomena and put some of their intentions into it, which was also a kind of helplessness and expectation that nature could not control.

In fact, it rains the most in May and the weather changes the most, so it is not surprising when it rains. It is not surprising that it rains on the Dragon Boat Festival. It's just that the ancients thought it meant too much rain, which was not good for agricultural production. After all, it rained on the Dragon Boat Festival. It should have been sunny. The ancients didn't think it was abnormal weather, but these didn't have much scientific basis, just speculating and judging climate change, which would be inaccurate.

The ghost in July and a half refers to the Ghost Festival, because the fifteenth day of the seventh lunar month is the Mid-Autumn Festival, which is also the legendary Ghost Festival. In reality, there is no substantial impact and harm, but the abnormal climate of the Dragon Boat Festival will affect family and social life, and the flood will actually affect life safety. Therefore, May is more direct and has a much greater impact than July. July 15 is virtual, but the Dragon Boat Festival in May is physical. Of course, physical makes people feel more direct.
