Long, long ago, two large vultures came flying in the sky. Fighting over a piece of fatmeat, they chased each other and soared up and down.
At this moment, She Tu, King of the Tujue State, drew out two arrows,gave them to a man named Zhangsun Sheng and ordered him to shoot down these twolarge vultures.
Zhangsun Sheng adopted the shooting posture. When the two vultures were biting intothe fat meat and grappling with each other,he at once let fly the arrow and shot them at the same time.
