For amateurs do not have too high requirements, just have an interest in the guzheng above, cultivate the sentiment, but for professionals who want to have a better development of the guzheng above the book, paintings, video discs is impossible to tune the strings, change the score, if there is a professional aspect of the teacher, it is much simpler.
Of course, at the end of the day, whether you learn on your own or you find a teacher to teach you, the power is in your hands, so my advice is that you can listen to it or you can learn on your own.
Some friends who love guzheng are worried that they are too old to learn guzheng by themselves, in fact, there is no age limit for learning guzheng, the key is to be attentive, diligent and persistent.
