Subject + 已 + 完毕
The adjective 完毕 (wánbì) means 'finished' or 'completed,' indicating that a task or process has been fully concluded. It is more formal than 完了 or 完成 and is commonly used in written and official language. It often appears after a noun or verb phrase with 已 (already) to confirm completion, as in 已完毕 (already finished).
