Let's take a look at Gansu's operas first, because Gansu is more inclined to the northwest than Shaanxi, because the folk customs in the northwest are still relatively tough, and people's personalities are relatively straightforward, and there is no shyness in the south. Therefore, it is normal to play martial arts, but Shaanxi is a place with profound cultural background and is naturally a literary drama.
Then the Qin opera. As far as I know, Shaanxi is rich in culture, so there are many cultural people and many natural plays. Then Gansu belongs to a relatively simple place, and then people like to go to see operas. In this case, it belongs to the cultivation of drama, which can be described as complementary existence.
This is actually my main understanding of the sentence "Shaanxi opera, Gansu opera, Gansu martial arts opera, Shaanxi literary opera" I don't know if this is true, but it makes sense according to the local customs and cultural background. I wonder what your opinion is. Welcome to leave a message for discussion.
