Why doesn't the teacher teach you calligraphy directly?

Calligraphy, like learning methods, should be summed up by yourself. Just like learning, teachers can only teach you knowledge, not methods! If you really like learning calligraphy, you should practice it seriously. Practice every day if you want to practice well, and you don't need a lot of 5~ 10! Find a book you like. Don't write on it. Practice in it! Teachers don't teach you because you don't understand what they teach you, just like truth, you can only really understand it after experience! To learn calligraphy well, we must understand its background, just like understanding the feelings expressed by the central meaning of a text! This will sum up more methods and characteristics in practice!
