Which major should I choose, electrical automation or mechanical design and manufacturing?

There is a difference between the two:

Electricity focuses on the study of electricity and electronics, while machinery is mainly about the setting and manufacture of machinery, but our major also offers courses on mechanical design.

There are differences and connections between the two:

Electrical engineering and its automation-belonging to the School of Electrical Engineering. This major trains wide-caliber "compound" senior engineering and technical personnel who can work in the fields of system operation, automatic control, power electronics technology, information processing, experimental analysis, research and development, economic management and computer technology application related to electrical engineering.
