The girl who studied machinery didn't do this major when she just graduated. Can she turn back now?

I am engaged in mechanical design, but I am a man and started my old job as soon as I graduated. It's hard to find a job in your situation. Go to job fairs more often. Sending resumes online is basically useless. You can start with paperwork, such as making assistants, and slowly learn drawing network technology.

I am a second book, and now it is the fifth year. Painting is actually very hard, and the work is tiring and boring.

If you have no problem with drawing and drawing software, just find a design.
