A paper butterfly is lost and longing for home. A dragon offers her a ride home on his back — if she can solve the riddle “What was made in China 2000 years ago and is still used today?” To find the answer, she flits far and wide, to Beijing’s Forbidden City, to the Great Wall, and finally to the walled city of Xi’an. Just when she begins to despair, she meets another paper butterfly, who claims to have the riddle’s answer. Is it the right one? Lively collage illustrations introduce carp, pagodas, stone lions, and other elements of Chinese culture and family life.
