What is the solar term behind the awn?

After the awn is the summer solstice solar term.

Summer solstice is the tenth solar term among the twenty-four solar terms, and the fourth solar term in summer is the second solar term in midsummer. The time of awn seed is June 5-7 every year, and the summer solstice is June 2 1-22 every year. Every year when the sun reaches 90 degrees of the yellow meridian, the solar terms change from awn to summer solstice, and the daytime is the longest in a year. 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 south from the Tropic of Cancer, and the days in the northern hemisphere began to shorten gradually. For China, which is located in the north of the Tropic of Cancer, after the summer solstice, the height of the noon sun begins to decrease day by day; For China, which is located in the south of the Tropic of Cancer, after the summer solstice, the height of the sun returned to the south at noon, and it began to decrease day by day after the sun shone again.

Phenological phenomena:

In some ancient Chinese literary works, the summer is divided into three periods: the first period is stag antlers' solution, which means that the deer's horns are forward, so they belong to Yang. It is believed that the antlers begin to fall off in summer, while Mi is Yin, so they fall off in winter (Mi and deer belong to the same family, but the ancients thought it was Yin and Yang).

When the cicada starts to sing, it means that after the summer solstice, the male cicada will flap his wings and sing. Pinellia ternata was born in the third season, which means that Pinellia ternata is a shade-loving herb, named after it was born in swamps or paddy fields in midsummer. It can be seen that in the hot summer, some creatures that like yin begin to appear, while those that like yang begin to decline.
