Ask for advice. If the books in the library are lost, they must be returned within three days, and you have to pay three times the money. How to buy it in a bookstore? I am in Laishan, Yantai, which is very close to here. No matter how you buy it, the library has a special seal and you can't buy it online. This matter is easy to solve. You can send a book online by express delivery, buy some fruits with the book, find a librarian, and put in a good word to pretend to be a grandson to show your sincerity. He's not sick. How can you be embarrassed?
