A plateau region north-east of the Himalayas, Tibet was incorporated by China in 1950 and currently an autonomous region within China. The conflict between many Tibetans and Chinese government has been nonstop as many demand religious freedom and more human rights. In March, 2008, a series of protests turned into riots in different regions across Tibet. Rioters attacked Han ethnic inhabitants and burned their businesses, resulting dozens of death.
The eye train
The blazing sunlight of Tibet's high plateau may create an austere beauty, but its harsh rays give Tibetans the highest incidence of cataracts on the mainland. Thanks to a mobile hospital train called the Lifeline Express, funded by Hongkongers, many Tibetans have regained their lost eyesight. The train's team of ophthalmologists provide free cataract treatment for poor people on the mainland, including this trip to Tibet last month.
