How is the treatment of Tangshan Delong Iron and Steel (Laoting)? Is the working environment and promotion opportunities great? Good friend, can you help me?

The three-shift work system is the night shift last week, then the middle shift last week, and then the day shift last week. In this cycle, there are two close changes. For example, after I finish the middle shift, I rest for 8 hours (12 from night to 8: 00 am), and then I work in the day shift, and I am only given four days off a month. Working environment. . . I hate to break it to you, but steel mills are all the same. They are dirty, tired, hot (especially now), dangerous, noisy and painful. We went to Tangshan Delong (metallurgical major) last year, and now we have walked more than half. As for promotion, if you go to the workshop, I'm afraid it's difficult to get promoted, because there is great competition in the workshop, and many of them rely on relationships. It's hard to get up if there is no one in the company. If you are lucky enough to go to the technical department, so much the better, at least not so hot and tired. As for promotion, it is not easy. Can I take the postgraduate entrance examination or the postgraduate entrance examination? I have resigned from there!
