I was jointly trained by the government. When I was abroad, the country had to pay about 10 million a year (including living expenses and round-trip air tickets), and I was exempted from all tuition fees by foreign schools. If you are a public doctoral student, the annual tuition and living expenses will be 100,000 to 200,000 RMB, and the doctoral degree will take at least three years. You can figure it out yourself. Moreover, the key to not returning to China is not a fine, not money. At the meeting before the last departure, members of the Scholarship Committee said that if you break the contract, you should investigate the responsibility of your domestic guarantor.
I don't think it is easy for the state to pay for training us. If you really want to go abroad, go back to China and serve for two years according to the contract before going out.
