I found this aphorism in my book of Korean aphorisms.
겨울 바람이 봄바람 보고 춥다한다 gyeo.ul ba.ram.i bom.ba.ram bo.go chup.da.han.da winter wind-SUBJ spring.wind try-AND cold-make-PRES The winter wind blows cold at the spring wind.
This refers to the fact that a rude person will insult and find fault with a well-behaved person. No rest for the wicked, or something like that.
