Such an amazing postcard, don't you think? On the card we can see an old woman, a member of the Akha hill tribe, smoking. When I heard Akha hill tribe, I immediately assumed that it's a tribe living in the hills. But I was obviously wrong... This is what Wikipedia says about hill tribes: "Hill tribe is a term used in Thailand for all of the various tribal peoples who migrated from China and Tibet over the past few centuries They now inhabit the remote border areas between Northern Thailand, Laos and Burma (Myanmar). These areas are known for their thick forests and mountainous terrain. The six major hill tribes within Thailand are the Akha, Lahu, Karen, Hmong/Miao, Mien/Yao and Lisu, each with a distinct language and culture."
Thanks to Nataša and her trip to Thailand I think no longer that hill tribes are tribes living in the hills. Hvala, Nataša!
