'宾价' (bīn jià) is a classical or literary term meaning 'courier for guests or envoys,' historically referring to an official or attendant assigned to escort, assist, and represent dignitaries—especially foreign envoys or high-ranking visitors—during diplomatic missions or state visits. The character 宾 (bīn) means 'guest' or 'distinguished visitor,' while 价 (jià) here is an archaic variant of 介 (jiè), meaning 'intermediary' or 'messenger'; it does not mean 'price' (a common confusion). Thus, 宾价 literally conveys 'a messenger for guests.'

This term appears primarily in historical texts, classical literature, or formal ceremonial contexts—not in modern spoken Mandarin. It reflects ancient Chinese diplomatic protocol, where specialized attendants ensured proper reception, lodging, and communication for foreign emissaries. While rarely used today outside academic or historical discourse, it occasionally surfaces in period dramas or official commemorations evoking traditional diplomacy.
