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

"It is important to be mindful of cultural norms when visiting Suwon. It is considered impolite to point with your index finger, so it is best to gesture with your open hand. It is also important to show respect to elders by bowing when greeting them. Additionally, it is important to remove your shoes when entering someone's home or a temple. Finally, it is important to be aware of the local customs and dress appropriately, as some clothing may be considered offensive," remarked another expat in Suwon, Korea.
