I am a girl from Gansu, with a college degree in fine arts and a primary school teacher qualification certificate. I want to find a school as a teacher in Tibet! What is the channel?

You can go through formal channels. Every year, all provinces and cities have recruitment. You should review carefully at home, pay attention to official recruitment, register online, take a unified written test, then, after passing the written test, attend an interview, and then hand in valid documents to enter the political review. After the political examination is passed, it is a physical examination. After passing, you will be informed to participate in pre-job training, and then you will become a formal teacher.
