1. If you plan to develop in Liaoning in the future and don't plan to go to big cities like Beijing, Shanghai and Shenzhen, a bachelor's degree will not hinder your development (but your professional knowledge is better). Of course, it is better to have a postgraduate degree. So if you can find a job that you are satisfied with now and don't go to a big city, there is not much need to go to graduate school. People can't just do technology all their lives, and programming is a youthful meal, so when you have a foundation in your career, you will inevitably turn from technology to management, so you can consider studying for on-the-job management graduate students in the future.
2. I want to travel to a big city, and I am ambitious, but living in a small city is uncomfortable. Then you still have to go to graduate school because there are so many talents in big cities. Besides, if you go to graduate school, I suggest you go to a better university. Liaoning University of Technology is so poor that it is difficult to get along outside. Of course, it's ok here in Liaoning, but it's not good to go to a big city. If you really can't get into a good school, you can do it here first, but you can contact the research institute (Chinese Academy of Sciences) in Beijing or other universities to do your graduation thesis, so that you can find a better job after graduation.
