First of all, learning the flute requires the strength of your cheek, so you may lose a little weight when you start learning, but just like we exercise other parts, when we lose weight to a certain extent, some parts will become bigger, so as long as you don't play the flute for a long time every day, it doesn't matter, you will lose a little weight, but don't expect him to lose too much weight. Learning the flute is not a boy's patent. Especially in today's society, there are few talents, so how can you come out to mix?
