1: Hobby Mechanical and vehicle is basically a research class, boring some. Manpower is also quite boring, all day to deal with all the staff files, documents and other things. Logistics and business administration have more opportunities to get in touch with the society.
2: Salary Mechanical and vehicle graduates salary is relatively stable, mixed with the more experience the more the salary will be, year by year growth. Manpower space is very small, logistics and business start will be a little more, but the potential is not great.
3: Comprehensive look if you are a boy then consider vehicle engineering and mechanical design and manufacturing and automation it can give you a stable life, food and clothing. Girls will consider the rest of it, the employment rate is not high, but find a job are good jobs, if the family has a doorway to consider the last three, no doorway to rely on the strength of it, learn mechanical or vehicle.
I don't know if I'm satisfied!
