Errentai

Errentai, also known as Errenban, Dawanyi'er, Shuangwanyi'er, and Bengbeng, is a genre of Chinese opera performed by two singers. It is popular in Fugu County and Shenmu County in northern Shaanxi, Hequ County in northwestern Shanxi, Kangbao County in northwestern Hebei, and areas near Baotou, Hohhot, and the Ordos Plateau in Inner Mongolia.
In 2006, "errentai" was listed as a national-level intangible cultural heritage by the government of China.
History.
"Errentai" traces its history back to the 18th century during the Qing dynasty. It originated in Shanxi and later spread to western Inner Mongolia, Shaanxi, and Hebei. The songs are derived from folk songs; as such, different styles are developed in different areas.
Performance.
"Errentai" is performed by two singers, one acting in the "dan" (female) role and another in the "chou" (male clown) role. Traditionally both roles were portrayed by men, but the "dan" role is typically portrayed by actresses today. The performers would sing back and forth. Stage props include handkerchiefs, folding fans, rattle sticks and paper or silk stripes.
The musical instruments used include the "dizi" (transverse flute), "sihu" (four-stringed fiddle), and "yangqin" (hammered dulcimer). The wood block (梆子; "bangzi") and "sikuaiwa" (四块瓦, a percussion instrument) are also sometimes used.
