What is the difference between mechanical and electronic engineering and traditional mechanical specialty?

There is a big difference between the two. Mechanical and electronic engineering mainly talks about some high-tech assembly line projects in society. For example, some robots will be used in assembly lines, which are developed by mechanical and electronic engineering. The traditional mechanical specialty is easy to understand, and it is aimed at some more traditional tools to learn. There is a big gap between the two. The knowledge learned is also two levels.
