I ran across this four-character idiom somewhere – exactly where, I don’t recall but it’s in my notes.
事事件件
사사건건
sa.sa.geon.geon
work-work-thing-thing
This means “each and every,” but with negative valences.
Usage:
사사건건 트집 = finding fault, blemish, crack
사사건건 간섭하다 = meddling, interference
[daily log: walking, 6.5km]
