To learn tea art, it is best to go to the tea producing area. I think you will learn better. This is my personal suggestion. If it is a pure interest, it is not a deep understanding, but a hobby, and you can learn it anywhere. If you want to learn the system, you'd better go to the tea producing area to learn it. I think it will be better. At the very least, you can go to Chashan in person to see and process tea, and the tea culture atmosphere in the tea producing areas will be stronger.
