During the past 50 years, China's central government has invested a huge amount of funds in education in Tibet, making Tibet the first place in China to enjoy free compulsory education in both urban and rural areas. Since 1985, the state has set up boarding primary and high schools in farming and pastoral areas, and covered all tuition as well as food and lodging expenses for students at the stage of compulsory education from Tibet's farming and pastoral families, according to the white paper titled "Fifty Years of Democratic Reform in Tibet" released on March 2, 2009 by the Information Office of the State Council, or China's Cabinet.
