The word "聘请" is a compound formed by combining two characters with related meanings: "聘" (pìn), which means to engage or hire someone, often in a formal or official capacity, and "请" (qǐng), which means to invite or request. Together, they create a single term that emphasizes a respectful and formal act of inviting someone to take a position, typically a job or professional role, carrying a connotation of esteem and a structured agreement.
