Chedeng, also known as "Chemomei", "Yaomeideng", "Chechedeng", etc., flourished in the late Ming and early Qing dynasties. During the evolution process, it absorbed the elements of folk tunes and developed into a form. It has a history of more than 300 years and is widely spread in Chengdu, Chongqing and the southwestern Han areas. Chedeng is sung in Sichuan dialect, with singing and dancing. The melody is high-pitched and passionate, lively and cheerful, easy to learn and sing, and widely spread. During the performance, the "Yaomei" dressed as a woman stands in the car, and starts and sways with the "leading singing" of the "ugly bridesmaid" holding a colorful fan and the "helping singing" of the "driver" pushing the cart or the "boatman" pushing the boat. The lyrics are mostly improvised, and the singing belongs to the banqiang style. It adopts the "start, level, fall" style. The level sentences are divided into the symmetrical sentence pattern of "upper level, lower level", which is convenient for singing thousands of lyrics of upper and lower level even sentences, and adding pre-introduction, suffixes, and interludes. The chorus of "The plum blossoms are falling" or "The lotus flowers are making the crabapple blossom" is its characteristic ending. The singing of Chedeng is accompanied by instruments such as "four-leaf tile" bamboo clappers and erhu. The rap tune has developed from a single section to a complete set of multi-sections, emphasizing the "upper and lower sentences" structure of the "flat sentence", which can reach more than a hundred sentences. It is used to sing character stories and is called "Chedeng tune". Based on singing, Chedeng has gradually developed into a systematic stage performance, using stylized movements such as appearance, appearance, stage steps, and body movements to match the singing and interpret the plot. Chedeng originally had traditional repertoires such as "The Lazy Man and the Egg", "The Stubborn Girl", and "A Handful of Rice". After the founding of New China, it also created works such as "Two Masters and Apprentices" and "Three Gorges Red Lantern" that reflect the style of the new era. At present, the art of Chedeng lacks successors and is gradually declining, and it is in urgent need of protection and inheritance. (No pictures yet, please provide.)
