The Qinqiang "Down to the East of the River" and the Yu opera "Down to the East of the River" are both traditional Chinese operas, and both share similarities in theme and plot. However, from the point of view of historical inheritance, Qinqiang "Down to Hedong" is earlier than Yu opera "Down to Hedong".
Qinqiang is one of the ancient Chinese opera genres with a long history and rich cultural connotation. And "Down to Hedong", as one of the classic plays of Qinqiang, can be traced back to the Yuan Dynasty, and after hundreds of years of inheritance and development, it has gradually formed a unique artistic style and performance form.
