I learned this aphorism from my book of aphorisms.
거북이 잔등에 털을 긁는다
geo.buk.i jan.deung.e teol.eul geulk.neun.da
turtle back-LOC fur-OBJ scratch-PRES
[One] scratches the fur on a turtles back.
This means trying to do the impossible. “Trying to shave an egg”? “When pigs fly”?
Something like that.
Don’t try to do impossible things, right?
