What's the name for 4-character Chinese character expressions like 천고마비 or 오리무중?

Question

The characters for 천고마비 mean 'sky high horse fat' and the word means 'autumn'. 오리무중 similarly means 'five ri(≈mile) fog centre' and can literally mean a very thick fog, or metaphorically, a state of ignorance or confusion. I love these little (often semi metaphorical) constructions! Do they have a special name in Korean?

Answer 1

Hello, the name for 4-Character called 사자성어 or 고사성어 (four character of phrases/ fables and phrases).

I like 사자성어 kind of 금상첨화 (Icing on the cake) literally means good things adds on good things, 칠전팔기 means 'If you fail seven times, try to eight' (If at first you don’t succeed, try, try again.)
