(First of all, it is necessary to understand: Electricity majors can be divided into two directions: strong electricity and weak electricity. In detail, electric power engineering and its automation (power system, factory power supply and transformation, etc.) majors are strong electricity, and electrical engineering and its automation are mainly strong electricity. Weak electricity is supplemented by weak electricity, and the majors of electronics, communication and automation are mainly weak electricity. Other further subdivisions are only distinguished during the postgraduate period. But no matter whether it is strong or weak, the basics are the same.)
