‘Rù xiāng suí sú’ literally means ‘enter the village, follow the customs’ — a four-character idiom expressing the idea of adapting one’s behavior to local norms and traditions when visiting or living in a new place. Each character contributes meaning: 入 (rù) = ‘to enter’, 乡 (xiāng) = ‘hometown’ or ‘local area’, 随 (suí) = ‘to follow’, and 俗 (sú) = ‘customs’ or ‘folkways’. Together, they form a concise, proverbial expression emphasizing cultural respect and situational flexibility.

This idiom is commonly used in discussions about travel, cross-cultural communication, immigration, or even workplace adaptation in different regions of China. It carries a positive, pragmatic connotation — not blind conformity, but thoughtful accommodation to shared social expectations. Native speakers often use it to encourage open-mindedness and humility in unfamiliar settings, especially where etiquette, dining habits, greetings, or gift-giving practices differ.
