A series of activities were held in Beijing to celebrate World Book Day in April. Some focused on helping children form a reading habit. To help parents select the suitable reading materials, a book list for children made by experts was recently released (发布) at the Chinese Museum of Women and Children.
The list called Kingdom of Little Bookworms is divided into two parts - one for children aged 3 to 6, and the other for those above 6. "We still don’t have an official system of reading levels in China," says Bai Bing, an experienced children’s book writer. More than half of the 35 books recommended（推荐）for children under age 6 are picture books in simple language, while the other 42 books for older children deal with wider topics and require better reading ability.
