How long does it take to learn guitar from Mr. Man of Huayi Musical Instrument Store? As a hobby, how is the course arranged and how much does it cost?

Four classes a month, one hour each, and the price is about 100. At this rate, I can speak for myself. If I have time to practice again, I wonder if I can learn to concentrate after a month. It is best to study for half a year! If you have eight classes a month, you can play by yourself for half a year, and it depends on your understanding and talent! If you have a hobby, you can decide your own time. How far do you think you can stop learning?
