Actually, it's about the same. It's just that there are more teachers of acoustic guitars, and there are more musical instruments or training centers for classes. Maybe some teachers will lower their fees. Small cities generally 50-60 yuan/day. Big cities will be higher, about 70-80 yuan/knot. Of course, the more famous teachers, the higher the fees, ranging from 100 yuan/class to 150 yuan/class or 200 yuan/class.
