About 100 leftover children from a small county of Suqian City in east China's Jiangsu Province were invited to the City Library on World Book and Copyright Day, which falls on April 23. They come from Huji Experimental Primary School of Shuyang County and have never been to a library before.

In China, with one or both parents going out to earn money, many children are left in their hometowns in the countryside. These children are called "leftover children".
