Chinese spending more money on buying printed books

Wang Chong and his friends gathered at underground train stations in the cities of Beijing, Shanghai and Wuhan for a few days in January with the aim of getting noticed.

As they got in and out of coaches-and they did quite a bit of that - they made sure fellow commuters saw them glued to the books they were carrying.

Their flash mob was to raise awareness of reading among Chinese, says Wang, who initiated the activity.
