Why does it rain every year during the Dragon Boat Festival?

At this time, it has entered the Meiyu period, which refers to the period of continuous rainy weather in the middle and lower reaches of the Yangtze River in China from mid-June to mid-July every year. At this time, the utensils are easily mildewed, so they are also called "mildew rain", and when the plums in the south of the Yangtze River are yellow, they are also called "plum rain" or "Huang Meiyu".

The time that the rain belt stays is called "Meiyu season", the day when the rainy season begins is called "entering the plum blossom", and the day when it ends is called "emerging the plum blossom". Weather characteristics: continuous rain, high temperature and high humidity. After the Meiyu ended, the rain belt moved to North China, and the Jianghuai basin entered high temperature and little rain.

In fact, there was a saying in ancient times that "it is a good year if it doesn't rain in Duanyang", which means that it is a good year if it doesn't rain on the Dragon Boat Festival, otherwise it is likely to make the crops harvest bad, so the people believe this saying and are afraid that it will rain on the Dragon Boat Festival, so their food for one year may not be settled.

In addition, there is a saying that "money can't buy the May 5 th drought", which also means this. People don't want it to rain on the Dragon Boat Festival. Because the fifth month of the lunar calendar happens to be when the wheat is ripe, people should harvest the wheat. If it rains heavily at this time, it will affect the normal harvest, and the wheat in the field is likely to sprout, which will affect the people's annual harvest. There is no food, which means that they will go hungry this year.
