2. Slight summer heat is the 11th solar term among the 24 solar terms in the lunar calendar and the fifth solar term in summer, which marks the official start of the last month of summer. On July 7th or 8th every year, when the sun reaches longitude 105, it is considered as a slight summer heat. Summer heat means heat, and a little summer heat means slight heat, which means the weather is getting hot, but it is not the hottest yet. This climate is basically the same in most parts of China.

3. The average temperature in the south of China is around 26℃ in summer, which is already midsummer. All localities have also entered the season with the most thunderstorms, often accompanied by strong winds, heavy rains and sometimes hail. Most areas in the south are flooded in the east and west, so drought and flood control measures must be taken as soon as possible to minimize the harm. In most agricultural areas of China, crops in China have entered a vigorous growth stage after the harvest in May of the lunar calendar and before and after the light summer, except for winter and spring wheat harvested in Northeast and Northwest China. Farming is mainly a variety of field management work, and topdressing and pest control should be carried out according to the growth.

Although light summer is not the hottest season in a year, it is followed by the hottest summer in a year. There is a folk saying that "it is hot in summer, boiling in midsummer", and the weather will become more and more sultry and humid.
