《搜神记·卷十一》
楚王就命令养由基来射。养由基刚拿起弓，那猿就抱着树木号哭起来。到战国时代，更羸对魏王说： 我能虚拉弓弦不发箭就把鸟射下来。 
及六国时，更羸谓魏王曰： 臣能为虚发而下鸟。 
The King of Chu then ordered Yang Youji to shoot it. As soon as Yang Youji picked up his bow, the ape hugged the tree and cried loudly. During the period of the Warring States, Geng Ying told the King of Wei: I can shoot down a bird with my bow without actually shooting it.
