'除...之外 (chú... zhīwài)' is a Mandarin Chinese grammatical structure used to indicate exception or standing out from a group. It literally translates to 'apart from' or 'besides' in English. It implies that something is not only this but also that, or someone is not only this person but also that person. It can be used with both nouns and verb phrases, and is often used in the context of making exceptions or highlighting a specific instance from a general group.
