It's hard to say exactly how much the tuition is. After all, I haven't learned it, and I can guarantee that it is cheaper than learning it.
There is no time limit for learning martial arts. You should feel that you can learn or learn enough.
Whether martial arts is good or not, I don't count myself, but Wudang Mountain has gathered many foreigners to learn martial arts. Let me say something easy to understand. Tai Ji Chuan is the pinnacle of Wudang Wushu. In scientific principle, it is related to mechanics, inertia and conditioned reflex. It is important to defeat yourself with a small amount of strength, borrow the strength of the other side, or increase your own attack strength to destroy your physical coordination and create attack opportunities for yourself. The application of conditioned reflex is related to acupoints. If you don't understand, let me give you an example first. If someone hits you, you don't hide, but swing your sleeves and gently move his fist to your side. Can he still coordinate? His strength is just right. If you add strength, he can't control himself. It didn't take you much effort, so you destroyed his physical coordination with his strength.
