游鱼不知
[yóu yú bù zhī]
'The Wandering Fish Is Unknowing' symbolizes people who are ignorant of certain matters due to various conditions. They are perhaps carefree, unaware, innocent, lost, lacking information or experience, or intentionally turning a blind eye. Sometimes this also hints at helplessness in certain circumstances, like fish being unable to control water quality but continuing to live in it.
