Valley rain
Gu Yu is the sixth of the twenty-four solar terms. It is also the last festival of spring, and it is the valley rain when the sun reaches 30° of the ecliptic longitude every April 19 to 21 every year, which originates from the ancient people's saying that "rain is born of a hundred valleys". At the same time, it is also the best time to sow seedlings and pickle melons and beans.
In the middle of March, since the rain, the earth has pulsated, and now it is raining in the valley of water. Rain reads as going to sound, like rain in my public fields. Gaigu sows seeds at this time, from top to bottom also. "At this time, the weather is mild and the rain is significantly increased, which has a great relationship with the growth and development of cereal crops." The moderate amount of rain is conducive to the rejuvenation of wintering crops and the sowing of seedlings of spring sown crops, and the so-called "rain and hundreds of grains" in ancient times reflects the modern agricultural climate significance of "valley rain". However, excessive rain or severe drought often causes harm and affects later yields. Guyu in the middle and lower reaches of the Yellow River not only points out its agricultural significance, but also shows that "spring rain is as expensive as oil".

Ancient China divided Gu Yu into three seasons: "The first hou ping was born; The second waiting dove whisks its feathers; The third is for Dai Sheng to descend to Sang. "It means that after the rain in the valley, the rainfall increases, the duckweed begins to grow, then the cuckoo begins to remind people to sow, and then the mulberry tree begins to see the daisheng bird.
Spring, is the color of life; It is the bright smile of the warm sun; It is a song of praise sung by the birds. Everything is a view of spring!
