光头强砍不到树灰太狼吃不到羊
[guāng tóu qiáng kăn bù dào shù huī tài láng chī bù dào yáng]
Light-head Qiang can't cut down trees, and Wolf-grey can't eat mutton. Refers humorously to cartoon characters whose pursuits always fail. Used in context of continuous setbacks or frustrations, also could reflect acceptance of reality.
