The document provides examples of using the Chinese word "回 (huí)" which means "back" in English. It can be used as a directional complement to indicate the direction of movement for a verb. Some common structures using "回" include "回去" meaning "back to", "回來" meaning "back from", and combining "回" with a place name to indicate moving back to that place. Several examples are given demonstrating its use after verbs like "坐車(ride a car)" and "走(walk)" to specify moving back home, to school, to a country, etc.

A direction complement is a complement used to describe the
direction of a verb. Verbs often already have some inherent
movement implied, but by adding a direction complement, it
becomes clearer where, exactly, that action is going.
