'Lǚxíngshè' literally combines three characters: 旅 (lǚ, 'journey' or 'travel'), 行 (xíng, 'to go' or 'to conduct'), and 社 (shè, 'society', 'agency', or 'organization'). Together, they form a compound noun meaning 'travel agency' — a business that plans, organizes, and sells travel-related services such as tours, flights, accommodations, and visas. It is a standard term used across mainland China, Taiwan, and other Mandarin-speaking regions.

This word appears frequently in everyday contexts like booking trips, reading advertisements, or discussing vacation plans. While often used as a standalone noun ('I contacted a travel agency'), it can also function attributively (e.g., 旅行社的行程, 'the travel agency’s itinerary'). Unlike English, Chinese doesn’t use articles before it, and it rarely requires measure words in casual speech — though 一家旅行社 ('one travel agency') is common when counting.
