"Qinglinkou Gaotai Opera" refers to a folk costume drama performance style that is popular and active in the ancient town of Qinglinkou, Jiangyou, in the northwest of Sichuan. Every year on the first day of the second lunar month, Qinglinkou in Jiangyou City holds a traditional temple fair. This local custom has been passed down for many years. At this time of year, people have to wear a high-rise and sing operas. It is highly ornamental, interesting and participatory. Because of its long history, it has become a custom. Every time the fair is held, there must be a performance, and there are crowds of spectators from all over the country. The performance of "Qinglinkou Gaotai Opera" does not require a stage or a theater, nor does it require professional artists to create momentum. Its main feature is: using artistic means to materialize the stories in folk legends into vivid artistic images and freeze them on the high platform in the form of drama clips, and then lift them up by manpower for viewing. This form of artistic expression is the experience accumulated by the majority of working people in the long-term life and practice process. It not only meets the needs of onlookers nearby, but also provides an opportunity for people who are a little further away to watch the play. This is the fundamental difference between Gaotai Opera and other forms of drama performance. Not only that, the performance of Gaotai Opera also cleverly combines theatrical modeling with folk binding techniques. It not only mobilizes the wisdom of folk artists, but also improves the viewing and fun of traditional drama. It puts well-known traditional opera pieces in a parade state, making it a form of mass cultural activity where "the play moves but not the people", so that more people can watch the performance of Gaotai Opera with ease. Objectively, it plays an interactive effect of "people don't watch the play, the play watches the people". With the progress of the times, now people use modern recording and broadcasting methods to play each drama clip with singing or music accompaniment along the way, making the ancient art of "Gaotai Opera" more three-dimensional, vivid, fresh and modern. Since the reform and opening up, with the improvement of the rural economic situation, the people have put forward higher requirements for their spiritual needs after their material life has been satisfied. We have reason to believe that the hardworking and wise people of Qinglinkou will carry forward their achievements, make persistent efforts and keep pace with the times in the face of new challenges and opportunities! Let the traditional folk art shine more beautifully in the new century.
