What is the main content of the adult calligraphy training class in Shangshuguan?

Starting with the brushwork of calligraphy, and finally talking about how to create calligraphy, I can't remember clearly. The adult calligraphy of Shangshuguan is incomparable to any calligraphy institution in Hainan. Professor Huang from Shanghai Normal University visited the classroom in person, which is a teaching method for calligraphy major in colleges and universities. There will be homework at the end of each class, and the students will bring their homework to Huang Dou for comments next time.
