The power bureau in our country should basically be the central directly under the authority, because the power sector is very important to our country. Our unit, ha, is a small department under the management of the unit, because the old cable is buried underground, and sometimes no drawings are left, so for example, if the pipeline is broken, the forklift will dig the pipeline, and sometimes there is no sound. This is a very dangerous thing for enterprises, because many precision machine tools are working. Once the power is suddenly cut off, the parts in the factory are likely to be scrapped. Therefore, the electric power bureau belongs to public institutions.
