Landscape changes in spring, mid-spring and late spring

Yangchun: beginning of spring: As soon as the east wind thawed, the stinging insects began to shake and the fish froze. It is said that the east wind warms and the earth begins to thaw. Five days after the spring, the stinging insects slowly woke up in the cave. Five days later, the ice in the river began to melt and the fish began to swim on the water. At this time, there are still broken borneol on the water, floating on the water like fish. Rain: Wait for Rex to sacrifice fish; Second, wait for Hongyan to come; Third, wait for the grass to sprout before persuading. In this solar term, otters start fishing and put the fish on the shore like sacrifices before eating; Five days later, the geese began to fly back to the north from the south; In five days, in the "moist and silent" spring rain, the spirit of the sun rises everywhere in the vegetation and begins to sprout. Since then, the earth has gradually begun to show a thriving scene. Zhongchun: Jing Zhe: When the peach blossoms first opened; Second, wait for the sound of Cang Geng (Huang Li); Three waiting eagles turned into pigeons. It is described that it is the season of peach blossom red, plum blossom white, orioles singing and swallows coming, and most areas have entered spring ploughing. When all kinds of insects dormant and hibernating in the soil are awakened, eggs will begin to ovulate in winter, so it can be seen that fright is a solar term reflecting natural phenology. Equinox: Waiting for the arrival of birds; Second, wait for Lei Nai to make a sound; Third, wait for the power to start. It means that after the vernal equinox, swallows will fly from the south, and the sky will thunder and lightning when it rains. Hunchun: Tomb-Sweeping Day: Dangtong Shihua; Second, the vole became a quail; See you after the rainbow. This means that at this time, first the white paulownia blooms, then the shaded voles disappear and all return to the underground caves, and then the rainbow can be seen in the sky after the rain. Grain Rain: Pingyi was born; Second, wait for the cuckoo to brush its hair; The third stage is Dai Ren's surrender to mulberry. After Grain Rain, rainfall increased, duckweed began to grow, then cuckoo began to remind people to sow, and then Dai Sheng birds began to be seen on mulberry trees. Each solar term is about 15 days. China calls "fifth day" equal "and" third class "solar terms, so a solar term is also called" third class ". According to the climate characteristics and some special phenomena at that time, the working people in ancient China named each solar term "three phases" to express the characteristics of the weather at that time concisely and clearly.
