It really belongs to the oil field! But it is the tertiary industry of subordinate units. It used to feel that it was the tertiary industry of the refinery, but now it seems to belong to the group company. To be exact, it has nothing to do with the oil field. Do you want to go in? If you are a salesman, you have no future. It seems that you can't ask this question. I suggest you give up the idea of going there as soon as possible. Even the leaders there (incorruptible) can't make much money. At most, they can take things home and give gifts occasionally, but the purchasing department is different. You can earn kickbacks, but only you know if you have this way to get in. Not as good as the company in Bincheng Supermarket.
