Character by character
Origin and story
Philosophical anecdoteHuainanzi (淮南子), Dao Ying (道應), places this idea in a lesson attributed to Confucius. At Duke Huan’s shrine, he sees a vessel that stands upright when partly filled but overturns when full. Asked about maintaining fullness, he explains that things decline after reaching their height: joy can turn to grief, the midday sun moves west, and the full moon begins to wane.
The lesson advocates restraint and humility rather than the belief that happiness itself deserves punishment. Shiji also preserves a related warning in Chunyu Kun’s advice against excessive drinking. The later idiom describes delight that ends in sorrow, especially when excitement leads to excess or carelessness.
