What is the annual income of middle-level cadres in power plants of the five major groups?

I know that the director of the maintenance department in the power plant under Datang Nanjing Electric Power Company is a middle-level cadre, and the annual salary does not include in-kind benefits. It's in the early days of 10W, and definitely less than 150000. This is the income from deducting the insurance accumulation fund after tax, and the year-end bonus of 2W is also included. By the way, he said that in remote areas, such as Inner Mongolia Power Plant, there are more jobs and subsidies than him.
