I recommend you to study rail transit and automobile business. Today, with the railway as the main mode of passenger and freight transportation, the "Thirteenth Five-Year Plan for Railway Development" and the "Medium and Long-term Railway Network Plan" have been issued, which provides a basis for accelerating the pace of railway construction. This means that the demand for talents in railway units will only increase in the future, but at present, the demand for railway-related graduates is in short supply. Successfully entering the railway bureau means having a golden rice bowl, strong career stability, and very broad prospects for both salary and employment development. According to the international standards for the allocation of urban rail transit professionals, at least 60 management and technical personnel are needed for each kilometer of rail transit line; Each subway line needs about 1000 professionals. It is estimated that there will be about 3 1 1,000 new employees in 2023, which shows that the demand for rail transit professionals is huge, the demand for graduates is basically in short supply, and the prospects for career stability are broad.
