The province of Mae Hongson is surrounded by mountains. This gives to this place a specific microclimate and the name of “Muang Sam Mok” or City with three fogs. Throughout the years Mae Hongson is under the mists (winter mists, summer smoke fires and monsoon water vapors). Mae Hongson shares borders with Burma. The road to get there is a mountain road winding between mountains and valleys with more than a thousand turns. This impression of isolation has attracted many minorities who have emigrated out of the Shan state in Burma. Nowadays, the population of Mae Hongson is partly formed by the Karen, Lisu, Hmong and Lahu peoples. Every year the feast of the Poy Sanglong (ordination ceremony of the young Shan boys) is a regional holiday.
