Due to the rapid development of communication networks, the number of Chinese smartphone users has grown at an alarming rate in recent years. This has dramatically changed the ways of reading for many people. They now often read news and articles on their smartphones instead of buying traditional newspapers. The development of a large number of mobile apps enables people to read novels and other forms of literature works on their mobile phones. Therefore, the sale of paper books has been affected. But the survey shows that despite the steady growth of the mobile phone reading market, more than half of adults still like to read paper books.
