Generally speaking, there are four directions: the first is the coal company, which means going to the mine. This environment is not very good, but the treatment is good and the salary is high. The second is the Mine Design Institute, which means the salary is relatively low (the National Coal Design Institute is well paid, but it is particularly difficult to get in). The third is to go to the Coal Supervision Bureau, which belongs to a public institution, but it is not easy to enter because it needs to pass the civil service examination. Fourth, if you have a higher education, such as a doctor, you can stay in school and teach.
