It's good to learn PROE! There are many factories outside now, but you can't learn mold design without experience. I have a friend who studied mechatronics in college, UG. PROE, I can't find a job after I get out. Later, I went to a training school for half a year, and now I work in a company in Shenzhen for half a year with a salary of only 1500. But it's up to you. You can definitely get 3000 yuan by doing mold design for more than two years, but it is your ability to take it or not. I think whatever you do, just work hard. Study hard and don't think too much.
