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

"When visiting Yangon, it is important to dress modestly, covering your shoulders and knees, especially when visiting religious sites. Avoid touching someone's head, as it is considered disrespectful. Do not point your feet at people or religious objects, as feet are considered the lowest and dirtiest part of the body. Show respect to monks and elders by bowing slightly when greeting them. Refrain from public displays of affection, as they are considered inappropriate. Do not discuss politics openly, as it can be a sensitive topic. Use your right hand or both hands when giving or receiving objects, as the left hand is considered unclean. Finally, be mindful of local customs and traditions, and always ask for permission before taking photographs of people or religious sites," said another expat in Yangon, Myanmar.
