Looking at your experience, I feel that you have done a good job. It is hard to find a job now, and it is even harder to find a job with an after-tax salary of 2500. State-owned enterprises are very good, and Tiangang is also very good. If you feel that there is no development, then going to a foreign company will kill you. You can't climb too high, let alone going to a private enterprise, and you will earn less. If it is because of interpersonal relationships, I also advise you not to change, because crows are generally black, and everywhere is the same. Most people in large steel enterprises can't get in, and you probably don't want to go to a small one. Don't go to the steel mill. People may not want it. Why not consider big seamless? This place is nice.
