Lü Cao Di plot
In this story, a ping-pong ball floats by in a stream. Or a toy of the gods, as Bilike and his Mongolian cronies think. What follows is a search for the origin of the mysterious ball, along wise grandmothers and even wiser llamas. But no one has a clue. Until Bilike's father's TV set answers: the little white thing is China's national ball. And so the rascals have no choice but to go to Beijing and give the ball back to the nation.
