There are only two power grid enterprises in China, one is State Grid Corporation and the other is China Southern Power Grid Corporation. State Grid Corporation is the main body, and China Southern Power Grid is only responsible for the power grid operation in five provinces and cities such as Guangdong, Guangxi and Hainan. But Danjiang electric power company is a local power company, not belonging to the State Grid Corporation!
Some people think the national grid exam is easy, while others find it difficult. Last year, I got 76 points. Because I was not very studious before, I signed up for a class and had a manager who was at home for a long time. I have to say that the effect is quite good, and the key exams can also be tested, as long as the knowledge points are well grasped.
