Why is the pronunciation of Peking Opera not enough? You can't understand it without reading the subtitles, but the pronunciation of some local operas is very clear.

Peking Opera is a Cantonese accent in Zhongzhou. Except for some chanting, it is not Mandarin, nor Beijing dialect, nor is it a simple local dialect.

To put it bluntly, the singing of Beijing Opera is basically based on musicalized Hubei dialect and Anhui dialect, and the pronunciation of pronunciation is also based on sharp words (please search for relevant knowledge yourself). Compared with many local operas in northern dialect areas, such as Pingju Opera, Henan Opera and even Huangmei Opera, the language it uses is very different from Mandarin and northern dialect that people generally understand.
