老鼠扛枪上街找猫
[lăo shŭ káng qiāng shàng jiē zhăo māo]
It translates literally to 'A mouse carrying a gun goes on the street looking for a cat.' A whimsical, nonsensical phrase perhaps suggesting bravery beyond the expected size, capability, or nature - like challenging the predator one fears most. It's akin to confronting one’s greatest fear, often used humorously for its absurdity and bravery.
