When does the expression "Great Summer" mean?

Of the 24 solar terms in the ancient calendar of China, summer is the hottest. Its sign is that the sun reaches longitude 120 degrees. Mid-June in the lunar calendar and July 20th to early August in the solar calendar.

The twenty-four solar terms have been handed down since ancient times and are the crystallization of the long history and wisdom of the Chinese nation. It is recorded in Tongwei's Filial Piety and Helping the Gods: "It's mid-June, not summer, but the 15th day of Xia Hou. The small ones and the big ones are extremely hot, and they are divided into sizes. It was small at first, and it became big after reading it. "

Summer is hot. People are prone to heatstroke at high temperature, and it is also because it is too hot. The summer heat is around the midsummer in the dog days, and it is the heat after the summer heat.

As the name implies, the summer heat is more unbearable than the summer heat, which is the highest temperature season in the whole year, but it is the fastest time for all crops to grow in agricultural production.

At the same time, most parts of the country are dry and lack of rain, and the temperature can reach above 35 degrees. Frequent thunderstorms will occur in some areas, so in this season, while people are engaged in agricultural production, various natural disasters such as drought, waterlogging and wind disasters are also the most needed to be prevented.

It is popular to drink mutton soup and all kinds of food and drinks to relieve summer heat and enhance comfort and resistance.

In the long-term agricultural production, our hardworking, brave and clever working people have summed up some laws of climate change, which are still very useful today.

According to whether it is hot or not, we can basically judge what the weather will be like in the later period. For example, "summer is hot, and the field heads rest; It's cool in summer and the pond is full of water. " And hot summer, autumn will be very cool; Whether it is hot in summer or not, it will not be too cold in winter and so on.
