Luhai Research Institute in Panjin Liaohe Oilfield is not a platform for recruiting non-PetroChina employees, because PetroChina controls the number of new employees with few indicators. The scale of the institute can only be expanded in this name, but the treatment is the same as that of regular employees, and it will basically not become a full member. The employees in the same oilfield earn about 5W after tax every year, and they can't live on an empty stomach, but the benefits are quite good.
