This is entirely possible. The first thing is to learn something. Where can I learn? Hand-painted wall studio, of course. This is the fastest way and can be practiced. Actually, this is very simple. I am an art student in Normal University. I did this last year. If I have more business, I will still make a lot of money (I remember a classmate and I earned 500 yuan in one afternoon, 250 each). . . ), haha, not afraid of hardship. From the beginning of apprenticeship, you can draw some floor plans in two or three months. Moreover, now you can type directly with the projection, just start drawing directly, and even omit the step of drawing. It's easy to learn what you like. Do it with confidence and wish you success!
