Which is the hottest in summer?

According to the information of solar terms, the summer heat is the first solar term in summer, indicating that the weather is beginning to enter a hot state. It is hot before and after midsummer, and most parts of China are the hottest period of the year. In many areas of China, there are often high temperature days of 40 degrees Celsius, and the summer solstice occurs on June 2 1 or 22 of the Gregorian calendar. The biggest feature of this time is that the sun will return to the front line directly on this day, and it will decrease little by little during the day. The summer solstice represents the summer passing day by day. After the summer solstice, there will be more and more rainy days.
