What is the annual salary of PetroChina going abroad to Saudi Arabia?

It's hard to say. It depends on your level. The average worker earns 1 10,000 a month. Senior engineers can get 20-30 thousand a month, which is not good.

Of course, the environment is not very good. To do welding, it must be a line. That place is Gobi except desert.

In short, the salary is at least 2-3 times that of China.

Good wishes!
