Shooting Two Vultures with One Arrow

Long, long ago, two large vultures came flying in the sky. Fighting over a piece of fat meat, 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 Zhuangsun Sheng and ordered him to shoot down these two large vultures.

Zhangsun Sheng adopted the shooting posture. When the two vultures were biting into the fat meat and grappling with each other, he at once let fly the arrow and shot them at the same time.
