In Chinese, a verb or preposition is directly followed by its complement — the object or argument that completes its meaning. This head-complement structure is the basic way that verbs attach to their objects and prepositions attach to their noun phrases. For example, 在台湾 means "in Taiwan," where 在 is the head and 台湾 is the complement.
