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

"It is important to be mindful of cultural norms when visiting Tajikistan. It is considered impolite to show public displays of affection, so it is best to avoid kissing or hugging in public. It is also important to dress modestly, as revealing clothing is considered inappropriate. Additionally, it is important to respect religious customs, such as avoiding eating pork or drinking alcohol in public. It is also important to be aware of local customs when it comes to greetings, as it is considered rude to shake hands with the opposite gender. Finally, it is important to be respectful of local customs and traditions, and to avoid making negative comments about the country or its people," said another expat in Tajikistan.
