Graphic design can find a training class that can master graphic design software and see if it can be as cheap as possible. Learn the software well, and then find out if there are any advertising shops willing to take you. You can be an artist without advertising. After a year or two of work, I have gradually matured and can make some high-grade posters.
There are many training schools on the market now, but they are mixed. I think if you want to study, you must also want to find a professional school to study, like a national chain. This will not only save money, but also make full use of your precious time.
Once you learn, you can feel at home after going out to work and grow up quickly. Therefore, it is very beneficial for you to develop towards the goal of top designers or start your own business. Only those who are good at learning can do well.
