Zaozhuang is not a developed place, although there are many people.
For stability, it is best for state-owned enterprises. For example, companies in telecommunications often recruit people. Low wages are stable, unlike private enterprises. If it is fine today, I wonder if it will be fine tomorrow.
State-owned enterprises such as oil, grain and automobiles. Everything's fine.
I am from Zaozhuang, and now I am in Beijing. I wish you an early job!
