zhuān yè

professional

In Chinese, 'professional' is translated to '专业'. It is used in the same context as in English to describe someone who is an expert at his or her work or who currently engages in a specific specialist field. It can be used both as a noun and as an adjective based on the context of the sentence. For example, '他是一名专业的演员' means 'He is a professional actor'.
