Beijing Jiaotong University Weilian, how is this company? I have worked in the railway communications industry for 5 years, doing technical and management work.

First, any company built by itself under the name of a university or a large government group, unless it has a personal relationship with the boss, is generally not very good.

Secondly, if these companies do well, they can just decouple themselves from large companies by sharing some money.

Thirdly, I suggest you find a small private company to do it

Fourthly, you can choose to be a financial company, which offers low investment and high returns

Fifthly, I wish you success in your work, a prosperous career, and a healthy life
