Phenological phenomena:

In some ancient Chinese literary works, the summer is divided into three periods: the first period is the staghorn solution, which means that the deer's horn is forward, so it belongs to yang, and it is believed that the antlers begin to fall off in summer, while the mi is yin, so it falls 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.
