Is it a festival or a solar term to raise the dragon's head?

This is the festival when dragons look up.

Dragon Head Raising (the second day of the second lunar month), also known as Spring Farming Festival, Farming Festival, Qinglong Festival and Spring Dragon Festival, is a traditional folk festival in China. "Dragon" refers to the astrology of the oriental black dragon in seven of the twenty-eight lodges. At the beginning of mid-spring every year, the "Dragon Horn Star" rises from the eastern horizon, so it is called "Dragon Head Up".

The black dragon's seven nights correspond to rainfall. The ancients believed that dragons were in charge of rainfall, which determined agricultural harvest, and agricultural harvest determined people's living standards. Dragon has become the most important "totem" in agricultural society. In farming culture, "the dragon looks up" means that the sun is shining, the rain is increasing and everything is full of vitality.
