"Lusheng" is a reed pipe harmonic wind instrument, and is the earliest musical instrument created by the Miao and Dong ancestors. It is called "Ga" in Miao language and "Lun" in Dong language. Lusheng Festival is a traditional festival of the Miao and Dong people. In order to pray for good weather and good harvest, on the 15th day of the seventh lunar month every year, the Miao and Dong compatriots in Qiaoli, Jingzhou, Hunan Province, dress in their best clothes and gather from all directions in Lusheng Hall to participate in the grand Lusheng Festival. In 2006, the Miao and Dong Lusheng Festival was identified as the first batch of intangible cultural heritage list items in Hunan Province. According to historical records, the Miao people in Jingzhou "sang together with Lusheng" to "drive away plants and trees and encourage grains." It can be seen that "blowing the sheng and stepping on the hall" is mainly a ritual to pray for good weather and good harvest. It is a traditional folk cultural activity formed by the Miao and Dong people in their long-term farming life and rice-growing customs, with the content of entertaining gods and people, and with singing and dancing, worship activities as carriers, and contains many cultural contents such as history, religion, art, and commerce. Folk legend in Jingzhou: In a year of severe drought, the Miao people of Forty-Eight Villages prayed to the Dragon God for rain. When they saw a green dragon holding a pearl in its mouth and about to rain, the greedy village owner shot the pearl onto Tangbao Mountain. So the Miao people of Forty-Eight Villages played the Lusheng and went up the mountain to look for treasure for the green dragon. The music was so deafening that the village owner fell from the high cliff and turned into a cow. From then on, this place was called Gunniupo. The green dragon got the pearl back, and torrential rain poured down in an instant. The farmers had a good harvest that year. From then on, the Miao and Dong compatriots in this area would go to Tangbao Mountain to step on the Lusheng three times every year. On the fifteenth day of the first lunar month, they stepped on the Lusheng to pray for good weather, on the fifteenth day of the seventh lunar month, they stepped on the Lusheng to thank the Dragon God, and on the fifteenth day of the tenth lunar month, they stepped on the Lusheng to celebrate the good harvest. With the development of history and long-term social practice, stepping on the Lusheng has become a grand, comprehensive folk festival that combines music and dance. On the 15th day of the seventh lunar month every year, the Miao and Dong people living in dozens of villages in the "Qiaoli" area wear their best clothes and gather in the Lusheng Hall from all directions to participate in the grand "Lusheng Festival". After the Lusheng teams of each village arrive, a grand opening ceremony of the hall is held first. The iron guns are fired three times, and the grand event begins. After the sacrifice, amid the sound of firecrackers, a burly man holding a big flag with the words "peace and prosperity, good weather and good harvests" waves all the way as a pioneer. The "Lusheng head" who is responsible for leading the performance blows the small Lusheng, repeatedly blowing around a tune three times, opening the prelude of "blowing the Lusheng and stepping on the hall". Immediately afterwards, the Lusheng teams of each village follow the order of arrival at the Lusheng Hall, and the "Lusheng head" leads the young men to play the nine-tone Lusheng tune in front, and the girls follow closely with fans in their right hands and handkerchiefs or bouquets in their left hands, dancing gracefully, with the Lusheng column as the center of the circle, and stepping on the "Eight Diagrams and Tai Chi Diagram" together. Finally, the first round ends with nine concentric circles, commonly known as "Cai Tang Dance". The Lusheng team that cannot make it to the first round will dance in the second and third rounds until the sun sets. At the beginning of the "Cai Tang Dance", the girls will dance in the corresponding tune played by the "Lusheng Head". All the playing is led by the "Lusheng Head", and then the big, medium and small Lushengs play together. The small Lusheng has a bright and delicate tone, crisp and melodious; the medium Lusheng has a round and smooth tone, which is soft and beautiful; the big Lusheng has a full and thick tone, gentle and deep, which is a complete Lusheng "symphony orchestra". "Cai Tang Dance" is generally divided into three types: entertainment, competition and sacrifice. Nowadays, it focuses on entertainment. The Lusheng players play while skillfully performing various dance moves. The girls follow the slow, fast, depressed and rising Lusheng tunes, sometimes light and gentle; sometimes jumping and exciting, men and women dance together, freely and unrestrained, with many styles. A poem in "Jingzhou Local Chronicles" says: "There are no better days than spring and autumn, the reed pipe field is on the top of Huishan Mountain, people meet in the front camp and see off in the back camp, they never understand the sorrow of parting"; "A team of Bai children blow dragon bamboo, the cave master rides a leopard with three shovels, they sing on the top of the mountain, the phoenixes fly in to stop the moving clouds".
