Hospital libraries wear bracelets.
First of all, dress in a literary way. Don't wear sportswear to the library. Don't wear Dai Fugu glasses and belt watches. It's best to bring an inconspicuous bracelet. Secondly, don't bring mineral water, it must be a water cup, and there must be half a glass of water in a transparent water cup. Buy a pack of paper towels and pull them. Third, don't bring too many books, for example, you are a science and engineering man, take your textbook, and then find a novel, such as a lover, and put it aside. Fourth, don't play with your mobile phone. Write on the draft paper next to you. The words must look good. Fifth, don't look at people around you often. You can read a book for a while, casually raise your head and drink a glass of water and continue to bow your head. Sixth, this seat is yours. You should come to this position often. Finally, the most important point is that the face value should be high.
