a trip or celebration that organized for government officials or business people and paid for by somebody else, especially using public money (政府官员的)公费旅游 Word Originlate Middle English: from Old French jonquette ‘rush basket’, from jonc ‘rush’, from Latin juncus. Originally denoting a basket made of rushes, especially one for fish (remaining in dialect use), the term also denoted a cream cheese, formerly made in a rush basket or served on a rush mat. A later extended sense, ‘feast, merrymaking’, gave rise to this current sense.
