The Yi bell dance, called "Kenhebei" in Yi language, is a traditional folk dance of the Yi people to commemorate the dead. It is mainly spread in Zhushi Township, Hezhang County in the northwest of Guizhou Province, and is also distributed in Caishen Town, Zhijie Township, Hezhen Township, Shuangping Township, Anle Township and other towns. Its history can be traced back to the era when the Yi ancestor Durdi enfeoffed six marquises in the 8th century BC. At that time, all the people of each vassal clan tribe were soldiers and formed a war horse team. When the king and the leader held a sacrifice to mourn the former king, the subordinates had to organize a 120-man army and horse team and dozens of singing and dancing teams to show the knight's style on the sacrificial song and dance field. During the dance, the horse bells in the hand should be shaken to control the rhythm, and the "bell dance" got its name. The performance of the bell dance is majestic, tragic, bold and rough. The two teams of dancers are like leaping horses and waving whips, coming towards each other, vertical and horizontal, orderly and changeable. The dancers sing first and then dance, and the song and dance are the same. The content of the dance is the traditional production and life scenes of the Yi people, which are simple and healthy. The dance is performed to the beat of drums and copper bells, and the sound of the bells sometimes sounds like heavy rain and sometimes like whispers. There are many difficult movements in the dance, which are as graceful as a startled swan and as dancing as a dragon, showing the bloody spirit of the brave and mighty Yishan men on the battlefield. When dancing the bell dance, the dancer holds a horse bell in the right hand and a ribbon in the left hand, and dances happily. In the past, "Kenhebei" was only allowed to be danced by young men, and the number of participants was generally 4 or 6. After the founding of New China, after adaptation, the performance form of the bell dance became more diversified, and there were major adjustments in the stage layout and formation interspersed, and the content also changed. It mainly shows the history of the development of the Yi ancestors who survived tenaciously in the struggle against nature, and generations of men farming and women weaving, living and multiplying. From then on, women were also able to participate. The Yi bell dance retains its original style and is the most complete, artistically valuable and widely spread folk dance form of the Yi people. It vividly reflects the national character and aesthetic taste of the Yi people, and has a huge influence in the entire northwest Guizhou region. In addition, the Yi bell dance is a living material for understanding the funeral customs of the Yi people and the beliefs, rituals, and customs of the Yi ancestors, and a model for promoting national folk culture, which has many research values. At present, due to the changes in the cultural ecological environment, the aging of the artist team, the changes in the environment, and the lack of talents, the "bell dance" is facing the risk of being lost, and it is in urgent need of rescue and protection.
