What are the origins and customs of solar terms in beginning of spring?

Origin of solar terms in beginning of spring: Since the Qin Dynasty, China has taken beginning of spring as the beginning of spring. Beginning of spring is divided from astronomy, but in nature and people's minds, spring is warm and flowers are fragrant. Spring is growth, cultivation and sowing. In climatology, spring refers to the period when the average temperature is between 10℃ and 22℃.

Beginning of spring solar festival custom: On the day of "beginning of spring", commemorative activities have a long history, which appeared at least 3,000 years ago.

Later, the location of Spring Festival activities was not only in the eastern suburbs. For example, in the Song Dynasty's Dream of Liang Lu, it was recorded that "beginning of spring Day, under the slaughter of ministers, celebrated when entering the DPRK." This proves that the Spring Festival has entered the palace from the countryside and has become a mutual worship among officials.

Phenological phenomenon

Spring has begun. In nature, the most striking feature is that everything is beginning to show signs of recovery. In beginning of spring, you can obviously feel the breath of early spring in the Tropic of Cancer and its south of China. The area north of the Tropic of Cancer can only be said to be a prelude to spring. Everything has not recovered yet, and it is still in the winter when everything is closed. For the area north of the Tropic of Cancer, the farther away from the Tropic of Cancer (where the Yellow River meets the pond), the later the spring comes.

Some ancient works of China divided the 15th beginning of spring into three periods: "The east wind thawed, the insects began to vibrate, and the fish became cold", which means that the east wind warmed up and the earth began 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.
