Why do you have to find a training class if you want to learn Go? I don't think many people learn Go to become professional players! More people just like it and want to take it as a hobby. Then, like me, you can find a few introductory videos of Go online, not a long story. Just explain the basics clearly, so much the better if it's interesting. Recommendation: Web links. Then find a chess platform, such as Yicheng Go and Tencent Go, register an account and start playing chess. As long as you play more, your level will improve quickly. I learn chess late. After the college entrance examination, I started off and on. Play three or four games a week, and in a year and a half, from Yicheng 18k to Yicheng 3D. I think most amateurs are at my level. Of course, after that, I can't go up any more, which is about this level.
