Compulsory education is only nine years. No 12 years. The "9+3 Free Education" project implemented in Tibetan areas of Sichuan (including other ethnic minority areas) is to send a few poor children to vocational and technical schools in their provinces for free after completing nine-year compulsory education. Other parts of the province also have relevant support policies, and there are also free and subsidy policies for children from poor families. You can learn more from the local Youth League Committee, Women's Federation, Education Bureau and other relevant units.
