As for the old state-owned enterprises in Shenyang, they have also developed well in recent years.
To put it bluntly, the problem of personal development depends on the individual. They are all very formal enterprises. You have the ability to go up a lot in a year. Without ability, I can't get up for several years. This is better than state-owned enterprises, unlike foreign enterprises, which have the ability to rise and fall, but they are finished without the ability.
There's nothing wrong with undergraduates at Dongda University. I am also an undergraduate of Dongda University. As for finding a partner, since you can enter these enterprises, it shows that you have something extraordinary. I hope you can find your own advantages, give play to them in your work, and find your own positioning and career planning. Maybe you have no ambition, but at least you can get a good result.
