[Perspective](https://chinese-idioms.yudis.dev/idioms/topics/perspective)

## When to use it

Describe a mixed-quality group or supply.

Often people or offerings; judge individuals fairly.

## Understanding the expression

Useful plants and weeds appear together, making the whole patch impossible to judge by one specimen. Modern use describes groups containing both reliable and poor members, or a market with uneven offerings. It warns against assuming uniform quality. The phrase can be harsh when applied to people, so specific standards matter. Recognizing variation should encourage careful selection rather than justify treating every member with suspicion or dismissing a whole field without examination.
