FAW-Volkswagen's recruitment problem, do they have to specify the recruitment major? (For example, I majored in 10 and 17). I majored in environmental engineering. Is that okay?

For campus recruitment, major is one of the main conditions, but it is not very detailed, and general major is enough. The company's formulation of majors can't be as accurate as that in the school, as long as it basically meets the requirements, such as machinery and automobiles, so I suggest you don't give up and continue to work hard. But don't go too far. Finding a job is not the same as taking an exam. There are many factors that affect it. Not just in one way. This is usually nonlinear. So you should relax your mind, broaden your horizons and measure in many ways. There is no best job, only the most suitable one. I wish you can find a job you like.
