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

"When visiting Mondulkiri, it's important to respect the local customs and traditions. Avoid touching someone's head, as it is considered the most sacred part of the body in Cambodian culture. Similarly, pointing your feet towards someone or an object of worship is seen as disrespectful. Public displays of affection are generally frowned upon, especially in rural areas like Mondulkiri. It's best to keep such expressions private. When visiting temples or other religious sites, dress modestly. Women should cover their shoulders and knees, and men should avoid wearing shorts. Avoid raising your voice or showing anger in public. Cambodians value maintaining harmony and face, so it's important to remain calm and polite, even in difficult situations. If you're invited to a local's home, it's customary to bring a small gift. However, avoid giving anything with a sharp edge, like knives or scissors, as they're considered to bring bad luck. Always ask for permission before taking photos of people, especially monks and other religious figures. Some may find it intrusive or disrespectful. Lastly, be mindful of the country's tragic history. The Cambodian genocide is a sensitive topic and should be approached with care and respect," mentioned another expat when asked about moving to Mondulkiri, Cambodia.
