Buddhists crawl from China to Tibet temple for pilgrimage

In Tibet, devout Buddhists are flocking to the holy city of Lhasa for an annual pilgrimage.

But for four pilgrims, simply travelling to the city is not enough - they have spent over two months so far, crawling on their hands and knees from their homes in neighbouring Gansu as a way of showing their faith to Buddha.
