What do you mean by summer heat and summer heat?

Summer heat means the degree of heat, and summer heat is a transitional solar term.

The summer heat is the twelfth solar term in the twenty-four solar terms of the China lunar calendar. On July 23rd or 24th every year, the sun reaches longitude 120 degrees. At this time, around the Mid-Autumn Festival, most parts of China are the hottest period of the year, and the climate is characterized by: "Dou refers to C as a great summer heat, and at this time the weather is much stronger than a small summer heat, so it is called a great summer heat." This is the hottest solar term in the year around midsummer. In many areas of our country, the high temperature of 40 degrees Celsius often occurs. In this extremely hot season, heatstroke prevention and cooling can not be ignored.

Summer is the first 14 of the 24 solar terms. Around August 23, the sun reached the longitude of the Yellow River 150 degrees. This is a solar term that reflects the temperature change. According to the "twenty-four solar terms", "go and go again, and the summer heat ends here." It means that the summer heat will end on this day, and the temperature in most parts of China will gradually drop, and the summer heat will soon pass. Especially in northern cities.
