Where is the material major assigned to Taiyuan University of Science and Technology after graduation?

It doesn't match now. Finding a job depends on your job requirements. If you want to find a counterpart, it is generally China Railway, China Communications, China Construction and other engineering bureaus, or cement, ceramic glass, steel, automobile manufacturing, new materials, heavy machinery and so on. If you don't like it, you can do non-counterpart work, sales, paperwork and so on. But you must be persistent and familiar with computers.
