Some experts say that Errenzhuan art is "a universe full of musical interest" for farmers, a life form and a carrier of catharsis. Errenzhuan music is known as "nine tunes and eighteen tunes". It is a collection of folk songs, yangko and folk music in Northeast China. It is the "local accent" formed by the long-term accumulation of wild and national customs in Guandong. Errenzhuan also has four basic skills like cross talk - singing, speaking, acting and dancing. Although "speaking" does not account for as big a proportion in Errenzhuan's performances as singing does, the real speaking is "holding the board, rolling the board, and dryly grabbing the words", without losing a word or a board, nor is it So easy. The traditional two-person dance art occupies an important position in the cultural history of Montenegro. Montenegro is rich in talents when it comes to developing modern two-person dance art.

Zhang Xiangchen, the master of Li Qingshan, a famous duet artist in Jilin Province, is one of the early artists in Heishan County. He has profound artistic attainments, especially proficient in techniques such as holding the board and digging out the board. The board groove skills are very hard, which can be seen from this. Errenzhuan, the four factions of East, West, North and South, represented by the Western faction Tui Heishan, which is characterized by Pantou, has indeed a long history.

Li Xiuyuan (stage name Xiao Yuexia), a well-known female artist from Montenegro, has a sharp tongue and a sharp tongue. She is famous in the art world for her "slow to listen to the taste and fast to listen to the words". Ma Li, a duo expert from Liaoning Province, spoke highly of her singing skills such as holding the board and rolling the board. Although the old man is nearly seventy years old, he still teaches his disciples the singing, body movements, fans, handkerchiefs and other skills every day. Over the past 20 years, more than 500 disciples have studied under Li Xiuyuan. This old man is playing the role of a bridge and link for the inheritance and development of the Montenegro duo. The locals jokingly call the old man a "county treasure" level figure.

There is a professional Montenegrin duo theater troupe in Montenegro, as well as several small groups of folk duo artists. Artists such as Li Xiuyuan, Zhu Guizhen, Li Wenlan, Jin Wenzhi, and Yang Shaozhe have retired for many years. Although they are in poor health, they have also cultivated many rising stars. Middle-aged actors such as Wang Lizhu and Lu Cuiping have always been active in the front line of performances. After Wang Xiaobao and Sun Lirong won the gold and silver awards in the first Zhao Benshan Cup Duo Twist Competition, with the popularity of the TV series "Liu Laogen", the two also followed the duo and became famous across the country.
