Why do you say it's a little summer and a big summer, drowning mice?

It is a proverb to kill mice in the heat. This means that it rains the most during the high temperature in summer. During the hot summer, although the temperature is relatively high, once it rains, the battle is really not small. At this time, the southeast monsoon will bring warm and humid air flow in the Pacific Ocean, and when it passes through the middle and lower reaches of the Yangtze River and Taiwan Province Province, it will suddenly rain heavily, often causing floods, and mice living underground and in corners will be drowned. ?

Affected by its geographical location, China has become the main climate in most parts of China. The characteristic of monsoon climate is that it will be hot and rainy in summer, which is beneficial to crop growth. Therefore, the slight summer heat not only indicates that the weather is about to start a hot mode, but also indicates that the whole country will usher in a wide range of rainfall, and the crops planted by farmers are about to start growing wildly.

With the arrival of the summer heat, the sunshine hours in the northern hemisphere of China are shortened and the days are getting shorter and shorter. It stands to reason that the shorter the time to receive direct sunlight, the lower the temperature should be. Why is the temperature still rising after the hot summer? This applies the knowledge we learned in geography class in senior three. Although the direct point of the sun gradually moves to the Tropic of Cancer, it is mainly in the northern hemisphere. Because the heat of the sun is very large, the heat consumed at ordinary times is not enough to offset the heat brought by direct sunlight, so the temperature is still rising.

As one of the 24 solar terms defined by China in ancient times, it fully embodies the wisdom of the ancients. There was no modern 365-day division in ancient times, but the clever ancients in China watched the sky at night and connected with the stars for one year, dividing 24 solar terms. Moreover, the way that the ancients divided a year into twenty-four equal parts was very standardized, which was not only conducive to our usual records, but also helped farmers to cultivate better.

Since its establishment, Xiao Xia has been deeply sought after by everyone, resulting in many unique customs and habits, such as the custom of "eating new things" in Xiao Xia, which is common in southern China, and jiaozi, which is common in northerners. In addition to these customs and habits that have been passed down to this day, there are some catchy sayings, such as "take a nap and change from drought to waterlogging." "A little summer heat, a big summer heat, watering the rats to death." And so on, on the one hand, these fully reflect the wisdom of the ancient working people, on the other hand, they also reflect the importance of solar terms.
