Shadow puppetry is an ancient traditional art form of Chinese folk art. Like other opera arts, it can not only interpret the world in a small space, but also present the grandeur of millions of troops. Today, this ancient art is still popular in Tongchang Township, Yimen County, and has become a rare rural cultural phenomenon in the local area. Speaking of Tongchang shadow puppetry, we must first talk about Yimen shadow puppetry. The history of shadow puppetry can be traced back to the Han Dynasty, and the Ming and Qing dynasties were the most prosperous and widely spread periods of shadow puppetry. According to relevant literature, Yimen's shadow puppetry was formed during the Qianlong period of the Qing Dynasty, and was passed on and developed by Guangdong shadow puppetry artists after they came to the local area for performance. It is understood that in the old days in Yimen, shadow puppetry artists often performed traditional repertoires such as "The Romance of the Gods", "Journey to the West" and "The Romance of the Three Kingdoms".

It is used in the county, Pubei, Shijie and other places. It is named because of its sad and euphemistic tune. The second is the Yunnan opera singing. It is said that in 1929, the Yunnan opera artists in the county organized and established the "National Music Special Training Hall". They not only sang Yunnan opera, but also sang shadow play with Yunnan opera civil and military scenes, and used Sheng, Dan, Jing, Mo, and Chou actors to complete the lines and singing of different roles in each repertoire of shadow play. And "a swarm of bees" is because the shadow puppet artists learned the characteristics of Sichuan opera high tune, with one person leading the singing and everyone helping. This kind of singing style is popular in Xiaojie and Liujie. The tune is lively and smooth, with a wide range, long interludes and strong rhythm, which is very similar to Pingtan and rap. When performing, people use a wooden stick to hit the horns to control the rhythm. One or two people can sing many roles in various plays. As time goes by, nowadays, Yimen will perform
