There is little free training in flower arrangement in Tianjin. If you want to know about it as a hobby, you can choose a professional flower arrangement training school, which usually offers free public classes or free experience classes on a regular basis, or activities in the same city. But if you really want to learn skills, I suggest choosing a professional flower arrangement training school to participate in the training.
As the saying goes, there is no free lunch in the world, even if there is one, it is very simple, so it is difficult to teach or teach the core technology for some free training, even if there is one, it is very simple.
