Dragon Head Raising (February 2nd), also known as Spring Farming Festival, Agricultural Festival and Spring Dragon Festival, is a traditional folk festival in China. Dragon heads up every year on the second day of the second lunar month, commonly known as Qinglong Festival. Legend has it that this is the day when dragons look up.

The formation of Erlongshan's rise in early February is related to the natural geographical environment. On February 2nd, the Dragon Head-lifting Festival is mainly popular in the north (there is little water in the south, so it is more popular to offer sacrifices to the land gods). Due to the perennial drought and lack of rain, surface water resources are scarce in the northern region, and the agricultural production that depends on it cannot be separated from water. The invasion of pests and diseases is also a major disaster for crops. Therefore, people's psychology of praying for rain and removing pests and diseases is reflected in their daily beliefs, and the Dragon Head-lifting Festival on February 2 is particularly important for people: relying on the worship of dragons to exorcise evil spirits and win happiness has entrusted people's yearning for a better life-the dragon god protects the world, people and animals are safe, and the grain is abundant. On the day when the dragon looked up, all the clothes belonging to the snake and the dragon were washed and all the bad luck was washed away.

It means that there will be more rain in the future, which is beneficial to farming. One theory is that the dragon king always looks up from the bottom of the sea on the second day of the second lunar month because he misses his lost daughter.
