It's very kind of you to say that learning guitar is 50 yuan. It's more expensive to find hourly workers now. Besides, it's 2020. What is the price? 50 yuan auditions are almost the same. Learn from a good teacher. At least from 200 yuan to 300 yuan every hour, the ratio of 1 to 1. This is still a tolerable environment. Shangguan guitar is recommended in the Second Ring Road of Beijing. The teacher graduated from Berkeley Conservatory of Music, USA, and has a very good reputation. I am his student, so I recommend it responsibly. 50 yuan doesn't study, so he goes to Bili Bili for free.
