A moment in time: Reading havens

In the 1980s, two self-taught students sit where they can find space in Shanghai's Fuxing Park to prepare for the college entrance exam.

On a typical evening in Beijing's SDX Joint Bookstore, readers sit and read long into the night in 2014.

After a successful trial of extending open hours into a 24-hour business, many more bookstores followed the practice and have been offering the country's book lovers a warm lamp for late-night reading.
