Understanding cultural etiquette is crucial when traveling in China, as it can impact your interactions with locals. For instance, it's customary to greet elders first and to avoid discussing sensitive topics such as politics. Additionally, when dining, it's polite to wait for the host to start eating before you do. Familiarizing yourself with these social norms will not only help you avoid faux pas but also provide a more enriching and respectful experience during your stay.
