Example
短视频行业发展太快，难免泥沙俱下，好作品和庸俗的内容混在一起。
The short-video business has grown so fast that the bad has inevitably come in with the good, and fine work sits side by side with vulgar stuff.
Tone: negative (criticism).
Usage and origin
The picture is a flood carrying mud and sand down with the water. Used of a boom, a market or a movement that grows so fast that the bad pours in with the good, often 难免泥沙俱下. Close to 鱼龙混杂 (lesson 3-11), which describes the mixture itself; 泥沙俱下 stresses the rush that brings it in.
