鱼的记忆只有七秒
[yú de jì yì zhĭ yŏu qī miăo]
'鱼的记忆只有七秒' translates to 'A Fish’s Memory Lasts Only Seven Seconds'. This refers to the common belief (though scientifically inaccurate) that fish have extremely short-term memory. Metaphorically, it may imply innocence, simplicity, or the fleeting nature of life.
