Hua Pian (Chinese: 畫片) (also called "Yang Pian" in northern China) is a traditional Chinese game in which miniature reproductions of paintings or images are printed on paper or card paper. The cards feature a picture of Hua Pian on the front side of the card and a word on the back side of the card. In the 1990s, the game was widely popular among children.
The game rules are quite simple: Use your hands to flap the card. If the card jumps to another side, you win. Otherwise the card stays on same side, which means you lose.
