An ancient poem describing the heat.

In summer, the strings should be warm, the wind should be warm, and crickets are hidden in the moss on the terrace. In the swimming pool in summer, the tree returns early. Tang Shen _ period is most suitable for summer heat, and typhoid fever is even more wonderful. Talk in summer. Deep courtyard, wisteria fragrance, lingering. I don't know about Xia Chan's fierce inflammation, but only Qingning pays attention to it. Autumn rain. Summer leaves cicada and autumn rain, and rain meets the sky in a misty way. Tick-tock is silent and always broken.

Summer is the eleventh of the twenty-four solar terms, at the end of the afternoon and the beginning of the month. The sun reaches longitude 105 degrees, and the festival is held on July 6-8 of the Gregorian calendar every year.

Summer means hot, a little hot, not very hot. Although light summer is not the hottest season in a year, it is followed by the hottest solar term in a year. There is a folk saying that "it is hot in summer and hot in summer, and it is steamed and cooked". Many places in China have entered the season with the most thunderstorms since summer.
