Training courses, expensive and cheap, mainly depend on whether you can learn something. If it is a pure hobby, I want to learn tea performance. Actually, there is no need to go to a training class. Buy several sets of tea sets that are the same as the online tea performance, and follow them every day when you are free. Of course, this is just an unintentional line. Then, if you want to learn the system, of course, you should find the most professional and systematic training school. Of course, learn the best and most comprehensive, otherwise the money will be wasted.
