Pay attention to etiquette. Queue when you should. Please keep a polite distance when queuing, and do not stand close (it would be considered as sexual harassment). Smoking is not allowed indoors, especially in restaurants, schools, hospitals, Station...wait? (Taiwan's Tobacco Prevention Law is really strictly enforced). Don't litter. There are trash cans in tourist places, so please look for them. (Some cities charge fines for littering, even if it's just a piece of toilet paper). Don't speak loudly when eating in a restaurant. Just make it loud enough for the other person to hear. There is no need to tell the world. 5. When the habits of the two places are different, if you encounter someone who is trying to persuade you, just accept it generously. 6. Some tourist places will use red lines. Surround it (EX: Queen's Head), which means it is not allowed to enter.
