The Tibetan diaspora has been going on for 60 years. After the Chinese invasion of Tibet, the Tibetan community was forced out of their homes to seek refugee in India, Nepal, Bhutan, United States, Canada, Germany, Switzerland, etc. Today 150,000 Tibetans live in exile. When China turned Tibet into a police state many made the journey on foot or horseback for 15 days across the Himalayas. However this is a very arduous journey and the Chinese government has cracked down on Tibetans attempting to flee this way.
In 2006, Chinese police shot and killed a 17-year-old Tibetan nun as she attempted to cross the Himalayas on her way to freedom. She was just a 20-minute walk from the border with Nepal when she died in the snow.
