别来无恙？

You usually say it right after seeing someone. It works as a standalone greeting or a conversation starter. You can add a name or title before it. For example, 王先生，别来无恙？ It sounds elegant and polished. Use it when you want to show you care about their well-being. It is like a warm hug in word form.

Use this when you haven't seen someone for months or years. It is perfect for an old classmate you run into. It works great for a former colleague at a networking event. If you are writing a letter or a thoughtful email, use it. It shows you have a good command of the language. It makes you sound sophisticated and sincere.

Do not use this with people you see every day. If you saw your roommate this morning, it sounds ridiculous. It is too heavy for a quick 'hi' to the barista. Avoid using it if the person is currently in a crisis. It assumes a period of 'no news,' so don't use it if you talk daily. It can feel overly dramatic if used in a very casual setting.

This phrase has roots in ancient Chinese literature and history. In old times, a simple illness could be life-threatening. Asking if someone was 'without illness' was a serious inquiry. It reflects the traditional Chinese value of health and peace. It carries a sense of 'the passage of time.' It is often used in movies when two rivals meet after years.

You might hear 别来无恙啊 to make it sound softer. In very formal writing, people use 别来无恙乎 for a classical vibe. Most people just stick to the four characters. It is a 'Chengyu' (idiom), so it is best kept as is. It is a timeless classic that never goes out of style.
