Tengchong is located at the extreme edge of the city with high mountains and far water. Many customs from the central plains have been preserved and inherited in Tengchong. Take the Dragon Boat Festival custom, people here "hanging Aihu, with continuation of life wisp, drink realgar wine, ans send rice dumplings chanting..." It is no different from the Han culture area.
