Meaning

Functions as a postposition meaning 'among' when following a group noun, or 'in the middle of' when following a process or event. It identifies a subset within a group or a point within an ongoing activity. It is more formal than 中 or 里面 in this usage.

The postposition 当中 serves two main functions in advanced Chinese. First, when placed after a group noun, it means 'among' and is used to single out items or individuals from the group, often followed by evaluative or selective statements. Second, when placed after a process noun or verb phrase, it means 'in the midst of' or 'during,' indicating that something occurs while the process is ongoing. Compared to the simpler 中 or 里, 当中 is more formal and emphatic, often appearing in written and academic contexts. The pattern Group + 当中 is frequently paired with scope adverbs like 最, 只有, or 有些 to make specific claims about the group. For processes, 当中 emphasizes that the action is still ongoing when the described event occurs.
