Villagers are being bothered by a male Asian elephant making frequent visits to their villages. Since wild Asian elephants were found again in Pu'er in 1999, more and more elephants are migrating here, from forests to villages, putting much pressure on locals. Despite measures like building elephant-proof trenches and grids, dispatching observers, setting up infrared cameras, and offering food to them, some of the elephants have learned to avoid the set-ups.
