Sajaseong-eo

In Korean, sajaseong-eo (Korean: 사자성어; Hanja: 四字成語) are four-character idioms, the analog of Chinese chengyu and Japanese yojijukugo, and generally but not always of Chinese origin.^[1] They have analogous categorization to the analogs in other languages, such as gosaseong-eo (고사성어; 故事成語) for historical idioms.
