How should I choose a barber or photographer?

These two high-level words are rich, but if the barber can't do it, it won't be so rich. You see, there are too many hair salons, hair salons and famous teachers everywhere now. I once met a big brother who came to Beijing to study hairdressing. He said that he studied under a famous teacher at home and abroad, and the tuition fee was several thousand a day. He followed him for ten days. Can you see how rich the owner is? But what about him? How far can he go after learning? Even if he is at a high level, he should type his name. How many masters are there like that? Feel better about photography. Think about it for a long time and compare it.
