入境而问禁，入国而问俗，入门而问讳。
释义Explanation
这句话教导人们，踏入一个新地方前，应先了解当地的禁令、风俗和避讳，以免无意冒犯他人。它强调在人际交往和社会活动中需具备敏感的观察力与适应性，体现了儒家“入乡随俗”的核心思想。这种尊重差异的态度，既是修养的体现，也是避免冲突、促进和谐相处的实用智慧。
This saying teaches that before entering a new place, one should first learn about local prohibitions, customs, and taboos to avoid unintentional offense. It emphasizes sensitivity and adaptability in social interactions, embodying the Confucian principle of “doing as the locals do.” Such respect for differences reflects personal cultivation and serves as practical wisdom to prevent conflict and foster harmony.
使用场景Usage
在出国旅行、商务洽谈或跨社区交往时，事先查询目的地的法律、礼仪和忌讳，能有效避免文化冲突。例如，赴穆斯林国家避免饮酒，访问日本进屋脱鞋，到别人家做客先问是否忌食某种食物，这些行为都深得古训精髓，展现出对他人的充分尊重。
When traveling abroad, conducting business, or engaging across communities, researching local laws, etiquette, and taboos can prevent cultural misunderstandings. For instance, avoiding alcohol in Muslim-majority nations, removing shoes before entering a Japanese home, or asking about dietary restrictions at a private residence all follow this ancient wisdom, demonstrating deep respect for others.
