The Chinese word **换成** (huànchéng) is a compound verb formed through a common grammatical structure where the verb **换** (huàn), meaning "to change" or "to exchange," is combined with the resultative complement **成** (chéng), meaning "to become" or "into." This **verb-complement construction** indicates that the action of changing or exchanging results in a transformation or a new state. For example, in the phrase "把美元换成人民币" (bǎ měiyuán huànchéng rénmínbì, "to change US dollars into Renminbi"), the action of exchanging (**换**) is completed with the specific result of becoming the new currency (**成**). Therefore, the word as a whole means "to change into" or "to exchange for."
