How should college students use mobile phones reasonably?

No matter what occasion, when not in use, it is best to put the mobile phone in a formal position that conforms to etiquette. Don't put it in your hand or hang it outside your pocket when not in use. Usually, the location of the mobile phone is: in the briefcase you carry with you (this position is the most formal), in the inner pocket of your coat; It's in the cell phone case on the belt. When in a meeting, the mobile phone should be entrusted to the secretary and conference staff, or it can be placed in an inconspicuous place, such as at hand, behind, in a handbag, not on the table. Women can hang their mobile phones around their necks, on their chests or between their wrists, which is not only convenient to use, but also decorative.
