The word **聘用** is a compound term formed by combining two distinct but semantically related characters: **聘** (*pìn*), which means "to invite" or "to engage" someone formally, often for a position or service, and **用** (*yòng*), which means "to use" or "to employ." When paired, **聘** conveys the action of recruiting or offering a position through an official or respectful procedure, while **用** specifies the subsequent act of utilizing that person's skills or labor; thus, the compound seamlessly merges the concepts of "invitation to a post" and "employment" to express the complete, formal act of hiring someone for a job.
