各有所长

This phrase usually acts as a standalone comment or a predicate. You can say 我们各有所长 (We each have our strengths). It is very flexible. You can use it to compare two people, two products, or even two cities. It often follows a comparison of different traits. For example, 'He is fast, but she is accurate; 各有所长.' It feels very balanced and fair when you say it.

Use it in a job interview to talk about team dynamics. Use it when friends are arguing over which phone is better. It is great for diffusing tension. If your parents are comparing you to your cousin, drop this phrase. It shows maturity and a broad perspective. Use it when you want to sound wise and objective. It works well in both writing and speaking.

Don't use it if one thing is clearly, objectively worse. If a car has no engine, it doesn't have 'different strengths.' It's just broken. Avoid using it in high-stakes emergencies where a clear winner is needed. Don't use it to describe physical objects that are identical. It requires a contrast in talent or function. Also, don't use it to describe negative traits. It is strictly for 'strengths' (长).

Chinese culture deeply values harmony and 'saving face.' This phrase is a linguistic tool for that. Instead of saying 'You are bad at math,' you say 'We 各有所长.' It comes from a long history of Confucian thought regarding individual roles. It suggests that society works best when everyone plays to their specific niche. It has been a staple of the language for centuries. It reflects a very holistic view of human potential.

If you want to sound more poetic, try 寸有所长，尺有所短. This means even a small inch has its uses, and a foot-long ruler has its limits. Another common one is 各有千秋, which is slightly more formal. It implies that both sides have long-lasting merit. In casual slang, people might just say '各有各的好' (Each has its own good points). But 各有所长 remains the most balanced and professional choice.
