Massage is more troublesome and can't be sustained. The unit is not very busy, and often works for a few days a month. I practiced flute at home for a while, and then I met many colleagues in the factory. They all said half-jokingly that I went to Korea for plastic surgery. It was so beautiful. Flutes are not expensive and easy to learn. I have a round face and I have some baby fat. After playing the flute for a while, I'm obviously much better. Maybe I can't play the flute very well at first, but I'll be much better after practicing for a week. That's what I learned.
