When we exercise, the first thing we should do is not to make noise. As a fitness place, the gym is a public place. The intangible rules that we must abide by are similar. Try to keep quiet and don't let your voice affect others. This is the minimum standard. If you listen to music, please put on headphones. If we leave too many traces of sweat on the instrument, which has affected others, we can also wipe it with paper towels or ask someone to clean it. A little high-quality behavior will bring us a good sports experience.
