What is the origin story of the famous Henan opera "Brother Liu speaks too slantly"?

Henan Opera, which originated in the middle and late Ming Dynasty, was developed on the basis of popular songs (folk songs and minor tunes) in Henan Province, and absorbed the singing arts of Beiqu Xiansuo, Shaanxi Opera and Zhou Pu Bangzi.

With the deepening of research and the confirmation of a large number of materials, especially in the process of compiling Henan Volume of China Opera Records, experts from all sides conducted extensive investigation and demonstration, and came to the conclusion that the earliest birthplace of Henan Opera was in the ancient capital Kaifeng and surrounding counties.

It is clearly recorded in Dream of Tokyo in Song Dynasty that there are Sangjiawazi, Beiwa and Ciliwa in Kaifeng, Tokyo in Northern Song Dynasty. Goulan tile houses are all over the city, and a Goulan shed can accommodate thousands of spectators. At that time, the large-scale drama "Mu Lian Save Mother" had been staged in Kaifeng.

Extended data:

Henan Opera has been continuously inherited, reformed and innovated on the basis of Henan Bangzi. After the founding of the People's Republic of China, Henan was called Henan Opera for short.

Henan Opera is famous for its sonorous singing, moderate intonation, clear articulation, mellow charm, liveliness, flesh and blood, and being good at expressing the inner feelings of characters. It is widely welcomed by people from all walks of life for its high artistry. Because its music accompaniment takes jujube bangzi as the beat, it was named Henan Bangzi in the early days.
