Subject + 向 + Direction/Person + Verb
向 (xiàng) is a preposition meaning "towards" or "in the direction of," used to indicate physical direction or the target of an action. Unlike 对, which primarily targets people, 向 can indicate both physical directions and people. It appears before the direction or person and before the verb.
