What is the difference between Quyi Drum and Errenzhuan and Beijing Opera, Sichuan Opera, Shaanxi Opera and Pingju Opera? Is the former short in history or different in expression?

Quyi is a story told by one or several people. A person can play multiple roles at the same time and jump out into the story.

In China's traditional operas and dramas, everyone plays a role and can't change roles casually. Many actors get together to interpret a story.

Personal understanding is probably different.
