What cultural faux pas should I try to avoid making in Taipei?

"It is important to be mindful of cultural norms when visiting Taipei. It is considered rude to point with your index finger, so it is best to gesture with your whole hand. It is also important to be respectful of religious sites and to dress modestly when visiting temples. Additionally, it is important to take off your shoes when entering someone's home. Finally, it is important to be aware of the local customs when it comes to dining etiquette, such as not sticking your chopsticks upright in your food," remarked another expat who made the move to Taipei, Taiwan.
