In the early years of Xianfeng in Qing Dynasty, this kind of "meditation tune" absorbed the artistic nutrition such as yangko, stilts, roller boating and Taoist sentiment in sister art, and developed into a performance with some dance movements, which was entered and exited by two roles of Chou Dan. On holidays, people gather around the fire dragon, and actors and bands perform in the venue. At that time, people called it "turning the dragon", so the "table for two" developed from the initial "meditation" to "plaything" or "two-person class" "Errentai" became a relatively complete art form, which began with the birth of the drama "Walking to the West" in the early years of Guangxu in Qing Dynasty. At that time, due to successive disasters in Shanxi, the working people in northwest Shanxi were forced to "go west." It is not difficult to imagine from the lyrics of "Walking to the West" that thousands of poor farmers are running on that vast ancient road, accompanied by endless desolation and loneliness, and they only use ditty to tell their misfortunes and endless homesickness. It was also at this time that Lu Ge, the song of suffering and the song of missing came into being as the important contents of the "two-person platform".

Mongolian is a nation with good songs. When a large number of Shanxi people came to Inner Mongolia, they composed music and sang to them about their experiences of pulling camels, hay, boats and farming. When Mongolians are happy, they will enjoy money and land. Since then, this art form has absorbed and integrated the musical language and drama composition of Inner Mongolia folk songs, and the art of "Errentai" has matured day by day. With the return of some wealthy people, the art of "Errentai" is not only deeply rooted in Yanggao County, but also affects northwestern Shanxi, southwestern Inner Mongolia, Yulin, Shaanxi, Zhangjiakou, Hebei and other places. However, in that era when Jin opera was regarded as "orthodox", the art of "Errentai" was difficult to be "elegant". In the long history, the pace of development is always slow. A hundred years of ugliness. Although there are more and more programs, there is still no drama that can reflect more complicated plots from content to form.

With the birth of New China, the working people gained political liberation. With the continuous improvement of people's living standards, the "two-person platform" has developed significantly. In Yanggao County, more than 80% of villages set up amateur theatrical troupes on holidays. On the basis of the original content, village offices, peasant associations and other organizations have written and performed their own works, injecting things that reflect the spirit of the times. Today, some old people still enjoy the drama of marital autonomy, Hu Laojiao betraying his relatives, revenge with blood and tears, and sending children to join the army. Soon, due to the observation and appraisal organized by the cultural department, the forms became more and more abundant, and "playing the beach" took to the stage along the village.

The music of Yanggao's "Errentai" is basically composed of brand songs and singing. There are no percussion instruments except "Four Watts" (of course, they were developed later). As mentioned earlier, in the past, due to frequent disasters in Shanxi, many people lived outside the mouth and brought the singing of "Errentai" to Inner Mongolia. And some people who returned home from "outside the mouth" brought back the local "Errentai" minor from Inner Mongolia, which influenced each other and brought out the best in each other, and gradually formed a unique singing style: both Shanxi characteristics and Inner Mongolia charm. Compared with inner Mongolia's elegance and smoothness, it is refreshing and neat; Compared with the rough and high-pitched Inner Mongolia, it sounds beautiful. The biggest difference between Inner Mongolia's "Errentai" and Yanggao's "Errentai" lies in the vocal method: Inner Mongolia pays attention to singing one or more sentences before singing, while Yanggao's "Errentai" pays attention to singing in circles. Because of the great differences in vocals, people call the vocals to the west of Suiyuan (Hohhot) "Xikou Tune" and the vocals to the east "Dongkou Tune". "Errentai" music, like other local operas, absorbs all kinds of opera music to nourish itself, except its own tunes. For example, "Little Door Opening" in Jin Opera and "Bayin Hang Gai" in Taoism. After processing and refining, it finally became its own thing. The aria of "Duet" can be divided into four types: "bright cavity" (free rhythm), adagio (missing beat), water board (2/4) and kneading board (1/4). Ming cavity has a loose beat, a high range and ups and downs like a long river. Adagio is euphemistic and tortuous, with smooth range and deep emotions, such as a trickle; The running water board is bright and clear, with clear rhythm, like a torrent after rain; Allegro is played fast, singing is hot, and words are combined, just like a torrent. The traditional duet has four modes, namely, C, F, B-flat and E-flat.
