The parents of a young boy born with 15 fingers and 16 toes are attempting to raise enough money to enable their son to undergo life-changing surgery.

The three-month-old boy, Hong Hong, has polydactylism, a congenital condition in which those affected are born with additional digits. He has two palms, but no thumbs on either hand.

Hong Hong lives in Pingjiang County in China's central Hunan Province with his family. His mother, who works in a factory in Shenzhen City, also has polydactylism.
