Characters
How it is used
- Set idiom meaning things keep emerging one after another, endlessly - 新的骗局层出不穷 (xīn de piànjú céngchū-bùqióng) new scams keep cropping up nonstop.
- Usually describes phenomena, problems, new products, or tricks appearing in an unstoppable stream; the flavor is often (not always) mildly negative or overwhelming.
- Functions as a predicate at the end of a clause, not before a noun: say 类似事件层出不穷, not 层出不穷的… as a smooth attributive. Contrast 屡见不鲜 (lǚjiàn-bùxiān), which stresses 'so common it's no longer surprising' rather than 'endlessly new ones keep appearing.'
