Are the Three Supports and One Support in Tibet necessarily Tibetans?

Yes Tibet's "three supports and one support" means that college students go to rural grass-roots units to engage in supporting agriculture, teaching, supporting doctors and helping the poor after graduation. The recruitment target of this post in Tibet is Tibetan college graduates, and other regions are not among the recruitment targets. At the same time, students are required to abide by the law, have good conduct and have the spirit of not being afraid of hardship.
