The meaning of solar terms in Grain Rain in 2023

The meaning of solar terms in Grain Rain in 2023 is as follows:

First, the origin of Grain Rain:

The origin of Grain Rain is explained in ancient books. Twenty-four solar terms say: "In mid-March, after the rain, the earth and paste pulsated. Now it is raining, and its valley is in the water. The valley is planted at this time, from bottom to top, hence the name. "

In mid-March, after the rain, the land became fertile, suitable for sowing millet and other crops, and after sowing, a new season of rain came, suitable for grain growth. Therefore, the sowing of grains in the future will be in this solar term, and there are two things that have the name of "Grain Rain" from the bottom up.

In ancient Grain Rain, the connection between valley and rain implied the meaning of "rain gives birth to hundreds of valleys", and also reflected the agricultural climate significance of "Grain Rain".

Second, Grain Rain's "third class"

Every solar term has the phenological theory of Three Represents, and Grain Rain's three climaxes are:

A Hou Ping began to live:

The duckweed here refers to duckweed, which grows in water and can't stand frost, so when the temperature rises and there is enough rain in Grain Rain, duckweed gets a suitable environment for growth and begins to grow.

The second time, the pigeon blows its feathers:

The cuckoo here refers to the cuckoo. When the cuckoo blows its feathers, it means that the cuckoo begins to comb its feathers. Because cuckoos can feel the change of the weather, once the temperature is right, they will come to live in the north, then start to sort out their feathers and start courtship. The temperature in Grain Rain is just right for cuckoo, so there is a saying that cuckoo blows feathers in Grain Rain.
