Let me give you an answer. I am a sophomore majoring in vehicle engineering in Lanzhou Jiaotong University. If the graduate students of vehicle engineering are better, they can enter the four research institutes of CSR and CNR when they graduate. The salary is not high, but it is better than entering the locomotive factory. I almost entered the locomotive factory, subway and railway bureau. In short, if I have nothing to do, it depends more on my own skills. I also know a lot about civil engineering. Everyone in our dormitory is a graduate student of civil engineering. In the future, the salary of civil engineering is good, but it is hard. If it is better, you can enter the Railway Survey and Design Institute 12345. However, there is a problem here at Jiaotong University, that is, there are too many people studying civil engineering and the employment competition is fierce. However, if you want to have skills, you'd better have a relationship with the tutor unit before you can enter. There are subsidies, but no scholarships. If the admission is voluntary, the tuition fee will not be paid, which will actually offset the scholarship. Ask me if you have any questions. Good luck.
