The Chinese word "返校" (fǎn xiào) is a compound word formed by combining the verb "返" (fǎn), meaning "to return" or "to go back", with the noun "校" (xiào), which is an abbreviation for "学校" (xuéxiào) meaning "school". This creates a verb-object structure where the action ("returning") is directed towards the object ("school"), resulting in the specific meaning of "to return to school". It is commonly used in contexts such as the end of a holiday or break, describing the act of students going back to their educational institution.
