What major is suitable for girls who want to study in Harbin Engineering University?
I think girls do better in liberal arts, such as humanities, economic management, or science colleges, or engineering, and those with strong control, such as automation, underwater acoustics and communication.
Sure, if you like. As long as you like it, it will be suitable. Moreover, only in the major you are interested in can you go further and drill deeper. There is no major that only boys can study.
