Rao Quan, director of the National Library of China, says the award aims to promote reading and to "stay close to readers" to improve the public's scientific and humanistic literacy.

Now in its 14th edition this year, the award nominated 1,562 books published in 2018 in three categories: social sciences, popular science and children's books. The number has set a new record. Books from 224 publishing houses were included in this year's award, a 40 percent rise over last year.
