Yin and Yang alternate health preservation in summer from solstice.

202 1 June 2 1, the summer solstice is the longest day and the shortest shadow in the northern hemisphere. It belongs to Yang in the daytime and Yin at night. At this time, Yang is extremely strong.

As the saying goes, the solstice in winter is "a sunny life" and the solstice in summer is "a cloudy life". These two solar terms are the key stages of the transformation of yin and yang, and are also crucial for health preservation.

Summer solstice phenology

At first, the antlers were untied. The ancients believed that the deer's horn was forward and belonged to Yang. From the summer solstice, Yin Qi was born, and Yang Qi began to decline, so the antlers felt that Yin Qi began to fall off. Elk is cloudy, so it falls off from the winter solstice. Second, the cicada began to sing. After the summer solstice, the male cicada feels that the yin is getting longer and longer, so he drums up and sings. Third, Pinellia ternata was born. Pinellia ternata, the medicinal name, was born in midsummer, hence the name. Pinellia ternata is a shade-loving plant, which is born in swamps or paddy fields in midsummer. At this time, it began to grow, germinate and gradually become a piece.
