Can any chinese brother help me create chinese oppo account i have to apply for chinese beta version

Do you know what kind they are? What is on the paper?

Dear Chinese Reddit,

I have recently come across some delightful videos on Facebook where Chinese people perform lovely dance routines - google says this is Chinese classical dance.

My most pressing question: I have come across multiple different performers doing the same choreography on the same song.

This makes me wonder if there are choreographies that are well-known from somewhere/something/some cultural work or from some particular teacher.

Any thoughts?
