Parents know that reading is important to their children, but they may not understand it, says Du Xiaoxin. Emotional picture books can help children understand their emotions better, she says.

Reading with relatively open themes can enable parents and children to embrace a relatively diverse world, Du Xiaoxin says. In some developed countries, even in the working class, half of the parents can accompany their children to read once a day, according to a Shenzhen survey. The study was conducted by the Shenzhen Aiyue Public Welfare Fund and Shenzhen Municipal Government.
