Dashi Chedeng Opera is a traditional opera in Zhejiang Province. With its unique cultural form and artistic charm, it has been popular in the Dashi Mountain area of Linhai for more than a hundred years. Due to the special geographical environment and traditional folk customs, Dashi Chedeng Opera has completely preserved the simple, rough, high-pitched Chedeng music and unique performance form. In June 2007, the Provincial People's Government announced that Dashi Chedeng Opera was included in the second batch of Zhejiang Province's Intangible Cultural Heritage List. Chedeng Opera has a unique performance form and is light and flexible. Generally, only six people are needed to perform in a Chedeng class. Let's take the plot of Guan Yu sending the emperor's sister-in-law out of the pass in "The Three Kingdoms" as an example. Guan Yu rides a bamboo-woven paper horse, with a horseman holding the reins in front, and "Chedeng women" on the left and right riding carts made of cloth, and behind the carts are "Chedeng dogs" pushed by two people. At night, lanterns are hung at the four corners of the venue. At the beginning of the performance, Guan Yu, who was riding a horse, appeared in the middle amid the sound of gongs and drums. The two women on both sides of the horse split to the left and right, walked in an eight-character pattern, visited four gates, and changed their positions. The horseman turned somersaults, and the "horse lamp dog" shouted "roar, roar, roar", which was quite powerful and pushed the performance to a climax in the passionate emotions. The roles of the horse lamp singers are generally divided into male and female roles. The horse lamp lady dresses up as a woman, Guan Yu sings the painted face, and the horseman and the horse lamp dog also play their own roles. Sometimes the band also sings the chorus. The main tunes include "Xi Pi", "Du Zi", "Er Huan", "Liu Shui", "Nü Gong", etc. The music structure is a variation of the banqiang, and the tune is a combination of rigidity and softness. It is rough and delicate, and is good at expressing the emotions of joy, anger, sorrow and happiness of various characters. The accompaniment instruments are mainly jinghu and banhu, as well as erhu, flute, and sanxian; the percussion instruments include big gong, small gong, cymbals, and bells. Dashi is known as the "hometown of car lights". Car light opera was most popular in the 1930s, when there were car light troupes such as Lingxia Wangcun, Yitang, and Yanxi. Among them, the "Yiqing Society" in Lingxia and the "Liang's Car Light Troupe" in Baibu were the most famous. In the 1950s, Dashi's "Lingxia Car Light Troupe" went to the province to participate in the folk art festival and won the second prize. Today, Dashi car light opera is still active in mountain villages during festivals.
