Daxian Opera was originally called Gongxingban, also known as Xianzi Opera. It is an ancient and rare polyphonic opera. It is centered in Kaifeng and Puyang, Henan Province, and is popular in the northeastern part of Henan Province, the southern part of Hebei Province, and the southwestern part of Shandong Province. It is generally believed that Daxian Opera has a certain origin relationship with the Liyuan Opera of the Tang Dynasty court, and in the process of evolution and development, it has inherited the tradition of the northern tunes of the Song and Yuan Zaju. There were originally more than 500 Daxian Opera repertoires, and about 100 are still extant. The content is mainly about the struggle between loyalists and traitors, killing and conquering, and eliminating tyrants and protecting the good. Representative repertoires include "Rebellion against the Five Passes", "Heishi Pass", "Selection of Generals in the Yang Mansion", "Battle of Luoyang", "Conquering the Southern Tang", "Sun Wu Zi Raising Troops", "Huanghua Temple", "The Story of the West Chamber", "Two Frame Mountains", etc. The singing music of Daxian Opera is in the form of qupai, which is mainly composed of five major sets of songs such as [Hailihua] and [Jiangtou Jingui] and Sanqu such as [Shanpoyang] and [Bubujiao]. In addition, it also partially absorbs the music of Qingyang Opera, Shipai Opera, Xiansuo Gaoqiang, Luoluo Opera and other folk songs. There are more than 400 qupai of various types, and more than 180 have been excavated and sorted out. The accompaniment of Daxian Opera is divided into soft field and hard field. The main instruments of soft field include sanxian, tin flute, big flute, transverse flute, sheng, etc. The tin flute is a unique instrument of Daxian Opera. The accompaniment with it is called fine music, and the accompaniment with big flute, flute, and transverse flute is called rough music; in addition to general percussion instruments, the hard field also uses four big fans, sharp trumpets and conchs to create a tense and exciting atmosphere. In the singing of Daxian Opera, the qupai are changed frequently, the syllable jump is large, and the actors use real voice to speak and false voice to sing. The roles of Daxian Opera include five male characters, five female characters and five painted faces. The painted faces are delicate and full of personality. Daxian Opera has preserved the traditional "jumping for promotion" drama and the "funny drama", "tie-twitching drama" and "bare-chested drama" in the Song and Yuan Dynasty dramas. Its performance is based on plum blossom boxing and Hong Quan, which is rough, bold, simple and thick. The body movements and stunts are performed with real swords and guns, which are thrilling. Some of the stunts such as "cutting willow rafters", "playing five colors", "hanging", "sleeping on a three-hole bridge" and "smashing tiles" amazed the audience. Whether in terms of repertoire, music or performance, Daxian Opera has basically maintained its original appearance, allowing people to feel the legacy of the Tang Dynasty military drama, Tang and Song Dynasty Daqu and Song and Yuan Dynasty dramas, and has a high historical research value. Since the 1990s, due to the increasing richness of entertainment programs, the performance market of Daxian Opera has continued to shrink. At present, Henan has only two professional performance groups, Puyang Daxian Opera Troupe and Huaxian Daxian Opera Troupe. Due to tight funding, the actors' income has been decreasing year by year, and the living and performance conditions have deteriorated rapidly. There is a lack of performing talents, and many repertoires, tunes, and stunts have been lost. Now there are nearly 100 tunes and more than 200 repertoires waiting to be excavated. There is only one person left who masters the music of Tang and Song Dynasty Daqu and Daxian Opera Qupai, and he is nearly 70 years old and urgently needs protection.
