Do I need a teacher's qualification certificate to teach Go and Chess?

Go and chess have teacher qualification certificates, but they are not necessarily required. For example, most Go teachers are amateurs with more than five stages, and most chess players are amateurs or masters of 1. Of course, the main reason is that you are good at chess, and the chess world will recognize you! Most chess education institutions will consider whether to recruit according to your certificate, so the grade certificate is more important!

I hope you are satisfied, thank you!
