Why all rural tibetan houses have sharp spikes on their doors and fences? Local Tibetan brown bear population is growing explosively in Tibet in recent years, bears take over rural regions in Tibet and even make inroads into the cities. Tibetan brown bears are protected animals and hurting them is a serious crime, so locals have to live with them and try to have their houses protected with long sharp spikes.

Increasing number of Tibetan brown bears follow tourists for food during this peak tourist season in Tibet, local governments issue warning to the tourists to watch for their safety while traveling in Tibet.

One tourist opens the window of his room in a hostel and finds a total of 6 Tibetan brown bears waiting out of his window.
