What is the difference between 개과천선 and 환골탈태?
I try searching in the dictionary, found that both have more or less similar meaning.. :/
Is the meaning really the same? Or it has any difference?

Question

Answer

I think they are almost same.

개 : change
과 : fault, bad things
천 : mend, move
선 : good

*in our dictionary, it means, 'mend one´s ways'

환 : change
골 : bone
탈 : take steal
태 : be pregnant
oh you need to know the origin of this words.

* turn over a new leaf

usually, we say '개과천선' for personality
and '환골탈태' appearance.

just 'USUALLY'
you can choose anything.

Answer

They are same in meaning.:)
