Although many people read online，books have not gone out of fashion，In Beijing，Guangzhou and Shanghai，lucky passengers may find books somewhere on the underground．

The Fair，an online publishing company，has put 10000books on the underground，planes and taxis to make people more interested in reading．This project is called "Mobook"．

"Mobook" gets its idea from "Books on the Underground"，a community project in London．The purpose of "Books on the Underground" is to encourage people to read more．Zhang Wei，the CEO of the Fair also wanted to do something in China． He sent an e﹣mail to Ms. Cordelia Oxley，the leader of "Books on the Underground"，describing his plan and explaining the rules of "Mobook"． The leader replied to him in just two hours，saying that she thought the idea was great and she would offer help if needed．

But "Mobook" project is a little different from that in London． It has its own online system．People who want to donate books must give their information online． QR code stickers（二维码标签） are then set to their addresses．The book owners should stick them on the books before donating books and readers can know where the books are with the help of QR codes．

"Mobook" is a hot topic．Now thousands of bookworms have already taken part in the project．Zhang Wei said，"I am happy to see more and more people share their views（观点）about the books online and enjoy the happiness that reading brings to them．"
