光头强抓不住熊灰太狼吃不到羊
[guāng tóu qiáng zhuā bù zhù xióng huī tài láng chī bù dào yáng]
This refers to a scene from the popular Chinese cartoon, where 'Strong Baldy (from Pleasant Goat and Big Big Wolf) can’t catch bears just like Gray Wolf can’t eat goats', highlighting a humorous way of showing repeated failure in attempts.
