The Hakka people first moved from the Central Plains of my country to the coastal areas due to wars and natural disasters. The coastal areas have abundant rainfall and rich products, and the Hakka people live a life of plenty. Legend has it that the Hakka people have close contacts with the Dragon King of the East China Sea. In order to thank the Dragon King of the East China Sea for timely rain, the Hakka people celebrate the harvest with water dragon dance every summer, which has become a custom. Later, due to the continuous wars, famines and plagues in Sichuan, it almost became a deserted place. The popularity of the coastal Hakka people was relatively high, and the government forced a large number of people to move to Sichuan. It is said that the Hakka immigrants who came to Luodai in the early stage suffered from drought. They experienced vicissitudes in their bitterness of looking forward to rain and water. Later, it was learned that there was such a legend in the history of Luodai: When Liu Adou, the prince of Shu in the Three Kingdoms, was playing in the octagonal well, he accidentally slipped the jade belt in his hand into the well. Adou hurriedly ordered the eunuch to dig the well to retrieve the belt. Unexpectedly, there was a storm when digging the well, and it was calm when it stopped. There was a storm again when digging again, and the jade belt could not be fished up, so it was named Luodai. They also learned that the octagonal well was the eye of the East China Sea, and its water was sweet and inexhaustible. Inspired by this, the Hakka people spontaneously combined the water dragon dance of their ancestors with well washing to pray for rain, and they got rain, and the Dragon King did not get angry, which was very effective. After that, even if there was no drought, the Hakka people in Luodai would dance the water dragon every Dragon Boat Festival to thank God for the good weather (they would dance the colorful dragon and the fire dragon on the Lantern Festival) and celebrate the good harvest. The fire dragon dance, along with the water dragon, has become a unique cultural custom of the Hakka people in Luodai. The Hakka dragon dance in Luodai is the most famous "Liujia Dragon", which is named because the participants are all from the Liu family of the Hakka people from Jiangxi. The Liu family has lived in Luodai Town for more than 300 years for 14 generations, and the Liu family has been dancing dragons in the ancient town on auspicious festivals for more than 300 years. Liujia Dragon Dance is directly developed from the ancient Chinese dragon dance. It has a long history and has been passed down within the family without interruption. Therefore, it has preserved many of the most primitive procedures and simple rituals of ancient Chinese dragon dance. The dragon dancers are all bare-chested, wearing only a pair of shorts, and move up and down; the spectators spray the dragon with fireworks and chase it from front to back. Fireworks are a symbol of wealth. The redder they burn, the more prosperous the fortune. Therefore, the dancers and spectators attack and defend, and the Liujia Dragon has become one of the most attractive activities in Hakka culture. The origin of Hakka dragon dance is as long as a thousand years. At the same time, it connects the Hakka culture of Luodai with the Three Kingdoms culture more closely, and also reflects the importance of dragon dance in the Luodai area at that time. This has a very important reference value for the inheritance and research of the Hakka people in the Central Plains dragon culture.
