Longtaitou Festival, also known as the Eryue'er Festival, is a traditional Chinese festival held on the second day of the second month of the Chinese calendar. The festival is a reflection of the ancient agrarian Chinese culture. In the tradition of Chinese culture, the dragon is believed to be the king of all creatures and the ancestor for human being. It is also believed to be in charge of bringing rains, and both of these are important factors in ancient agricultural society. It is called “Dragon rising its head”(Long Tai Tou) because the dragon was traditionally regarded in China as the deity in charge of rain, an important factor in ancient agriculture. It is sometimes also simply called“2 Month 2” for short.
