A public library in Qinhuangdao, Hebei province that was built on a beach has been popular among the Internet users. It was called "the loneliest library" since it looks like the only object on the beach and few people pay a visit. After more and more people learned about it, they started going and visiting for a tour. Now the library is the busiest and the noisiest. According to a staff member, almost 2,000 people per day visit.
