From midsummer solstice to staghorn cicada, where did Pinellia ternata's hibiscus glory come from?

The Book of Rites records the obvious phenomena of solar terms from summer solstice to solar term. * * * is divided into three phases: "The summer solstice comes, the antlers dissolve, the cicadas first sound, the pinellia is born, and the hibiscus is glorious." The ancients divided the summer solstice into three stages: antlers, cicadas and pinellia.

First class: Although deer and deer belong to the same family, the ancients thought they belonged to Yin and Yang. The deer's horn faces forward, so it belongs to Yang. On the solstice of summer, Yin Qi was born, and Yang Qi began to decline, so the front antlers began to fall off. However, because the elk belongs to the shade, it falls off on the solstice.

The second stage: the cicada began to sing, and when the male cicada gave birth to Yin Qi, it was past the summer solstice. The third stage: 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 yin-loving creatures began to appear, while positive creatures began to decline.
