Quzi Opera is a folk opera popular in the five provinces and regions of northwest my country. It originated from folk songs in the Ming and Qing Dynasties. In the late Qing Dynasty and early Republic of China, local operas with different styles were formed in various places, such as Dunhuang Quzi Opera, Huating Quzi Opera, Xinjiang Quzi Opera, Ningxia Quzi Opera, etc. The singing style of Quzi Opera belongs to the joint singing style, which is composed of many tunes. In the process of development, it also absorbed the artistic elements of Qinqiang and Meihu Opera. Its performance forms include stage performance and street singing. Among them, stage performance is commonly known as "color singing", with civil and military scenes and costumes and props, and the dialogue is in the local dialect. The performance requires the female role to twist happily, walk gracefully, dance lightly and lively, and have a vivid image. The clown role needs to be humorous and funny. Street singing is commonly known as a cappella singing, which is not restricted by the performance venue and does not require costumes and props. As long as the singer has a good voice, sings accurately, has many tunes, and has a stable rhythm, he can sit down and sing. The repertoire of Quzi Opera covers a wide range of themes, mostly showing mythological stories, historical legends and folk social life. As a local opera that once flourished among the people in the Dunhuang area, Dunhuang Quzi Opera has been circulated among the people for thousands of years. Today, there are still small-scale performances among the people during festivals. Studies have shown that although the content has evolved and new folk creations and new art forms have been added, the Dunhuang Quzi Opera, which has formed its own style, still retains the lyrics and tunes in the Dunhuang manuscripts, which has continued the remnants of Dunhuang culture among the people. Quzi Opera is mainly performed by amateur folks, and there are few professional performance groups. With the changes in society and the diversification of entertainment methods, the living space of Quzi Opera has become smaller and smaller, and it is now on the verge of being lost. In order to protect and promote Quzi Opera and expand its influence, relevant parties have taken a variety of measures such as holding Quzi Opera artist training classes, inviting old artists to concentrate on discovering, sorting out, and teaching Quzi Opera repertoires, and recording and recording repertoires, and have accumulated some valuable experience and information. On this basis, it is still necessary to consolidate the existing achievements and further deepen the rescue and protection work.
