There should be many.

but

Most of them are not real tea artist training courses.

but

Learning a so-called tea performance is actually just a demonstration of the process of making tea, just as tea.

I only taught "Tea Show" and some very common sense to cope with 80 multiple-choice questions +20 judgment questions, and 60 points were qualified. Finally, I went home with a tea artist's professional qualification certificate, but I mistook the certificate for a tea artist.
