Why is Guyu called Guyu?

The traditional 24 solar terms in China were originally formulated based on the needs of agricultural activities. Each solar term has a distinctive name, such as the Beginning of Spring and the Summer Solstice. With the arrival of the Grain Rain solar term, the cold wave basically ends and the temperature rises rapidly.
"Qunfangpu" says: "Guyu, the grains grow because of the rain." Before and after Guyu, the rainfall increases, which is conducive to the sowing and growth of crops.
From an astronomical perspective, the ancients determined that Grain Rain occurs when the sun reaches 30° of the ecliptic longitude between April 19 and 21 each year. At this moment, the rice seedlings in the fields are just being planted, and many crops have also been recently sown and need rain to nourish them, so there is a saying among the people that "spring rain is as precious as oil."
As the temperature continues to rise, flowers are blooming in many places, and trees are growing new branches. The vibrant plants are telling people that it is already late spring. In some areas in the south, it may even feel "hot".
