The solstice in summer is the turning point of the sun's northward movement. After the summer solstice, the direct point of the sun began to move southward from the Tropic of Cancer (23 26' north latitude). For the area north of the Tropic of Cancer in China, the height of the noon sun begins to decrease day by day from summer to the future. For the area south of the Tropic of Cancer in China, after the sun directly returns to the south from summer to the future, the height of the sun begins to decrease day by day at noon.

High temperature, high humidity and occasional thunderstorms are the weather characteristics from summer to the future. The summer solstice is in midsummer, that is, at noon, belonging to the sun; Although summer is full of yang and the daytime is the longest, it is not necessarily the hottest day of the year, so the heat near the surface is still accumulating and has not reached the maximum.

Since ancient times, people have the custom of worshipping gods and ancestors in the summer solstice. In addition, after the summer solstice, people generally drink Qingbuliang soup, herbal tea and sour plum soup to escape the heat.
