In the early stage of learning guzheng, you can choose to go to a large class. First of all, you should know something about guzheng and lay a good foundation for learning. In this process, I will examine whether I am really interested in guzheng and whether I have the determination and conditions to learn it. But this process should not be too long. If you are determined to study, you'd better choose one-on-one teaching. At this point, you have a certain understanding of guzheng, or have mastered some of the most basic foundations and skills. The teacher will teach smoothly. If you teach smoothly, you will naturally make rapid progress in your study. Personally, I think that large class teaching is only suitable for people who entertain themselves and have no clear goals and requirements for learning. If you want to study hard, you should at least teach one-on-one with the teacher. In this way, the teacher's teaching purpose is clear and targeted, which is beneficial to your study and future development.
