Seeing your question reminds me that I used to study in many places. Those teachers are not responsible at all, and the conditions at home are not very good. My father also paid a lot of money for my guitar study, but I was really sad. But because my father knew that I liked guitar, I was told that Mr. Cao from the Guitar Training Center taught it well. But at that time, Mr. Cao was just a tutor, and now a training center has been set up. Tell me, if you learn from this teacher, if you don't learn well, you will never learn again. I also found Mr. Cao Naigen with a try attitude. This study is only a few years, and I didn't go to college until I got the tenth grade. I will always remember my teacher's kindness. So when I saw your problem, I wanted to recommend my teacher to you. I hope you can learn your favorite guitar well.
