Chinese writer Ren Rongrong and American historian and critic of children's literature Leonard S. Marcus were awarded the Special Contribution Award at the Chen Bochui International Children's Literature Award, a major literary award in China that was unveiled Thursday in Shanghai.

These two writers were awarded for their remarkable contributions to the development of children's literature and cultural exchanges within the field.

Five books including "Uncle Mouse Gets Up Late," written by Ye Guangqin, won the Best Literary Works of the Year. Five other works including two Chinese books and three books created by Italian, Australian and Brazilian authors and illustrators were given the Best Picture Books of the Year award. 

Four stories were winners of the Best Single Piece of the Year award.

The award, named after renowned Chinese children's book writer and literary translator Chen Bochui, who was dubbed as the "oriental Anderson," was first established in 1981.

The selection process of this year's event was launched in March. More than 600 single pieces, literary works and picture books from 33 countries and regions participated in the competition.
