From
李商隐《
咏史》(Li Shangyin, Late Tang, 9th c.):
历览前贤国与家,
成由勤俭破由奢 (Surveying past worthies' states and households — success came from diligence and thrift, ruin from extravagance). Written as a verdict on dynastic collapse, the line became a standard household motto and has been cited by Chinese leaders into the modern era as an anti-corruption slogan.
