善于

The structure is very simple. Use Subject + 善于 + Verb/Noun. You do not need extra particles. For example: 他善于沟通 (He is good at communicating). It works for physical skills. It works even better for soft skills. Think of it as a 'professional' version of being good at something. It focuses on the quality of the action.

Use this in job interviews. It makes you sound competent. Use it when praising a friend's unique talent. It is perfect for performance reviews. You can use it in written bios. It fits well in networking events. If you see someone handle a tough crowd, use it. It sounds thoughtful and observant.

Do not use it for basic survival skills. Saying 我善于吃饭 (I am good at eating) sounds weird. It is too formal for tiny, everyday habits. Avoid it if you are just 'okay' at something. It implies a higher level of mastery. Do not use it for things you hate doing. It carries a positive, proactive vibe. Keep it for things that require some brainpower or technique.

In Chinese culture, modesty is very important. However, 善于 is a safe way to describe others. It focuses on the 'goodness' (善) of the skill. Historically, 善 meant virtuous or expert. Using this word shows you appreciate excellence. It reflects a culture that values self-improvement. It is a 'gentlemanly' way to acknowledge talent. It avoids the bluntness of more casual slang.

You might hear 擅长 (shàncháng) quite often. They are almost twins. 擅长 is slightly more common for hobbies or sports. 善于 leans toward methods and interpersonal skills. You can also see 精通 (jīngtōng) for 'mastering' something. But 善于 remains the most versatile. It is the 'Goldilocks' of skill-based vocabulary. Not too simple, not too arrogant.
