First: interior designers, professional skills requirements, CAD to draw engineering construction drawings, 3DMAX renderings to make renderings, and finally, you have to understand related materials, such as what kind of floor tiles, wallpaper, facade paint and ceiling. Of course, you must know the corresponding construction, so there are many requirements, and of course the development prospects are also considerable. If you do well, you can do your own design company, construction, design and get rich quickly. So this is a career that I suggest you try and do well.
Second: furniture design, I feel that you have learned so many courses to do this waste. This major only needs CAD, which can draw the perspective view of furniture, as well as the structural diagram, and the corresponding size and hole position of each plate, and the final feasibility is good. So it is equivalent to half a carpenter. It's easy to do it after starting a major, but the corresponding salary development is very limited, so it's difficult to achieve anything.
Third: furniture sales, you should be an art major. Do you have the potential to do business? No, you are extroverted, you like to communicate with people, you can make relationships, and so on. The most important thing is whether you have perseverance. Therefore, doing sales is a test, but if you have professional skills, it is best to be close to your career. If you want to try sales, you can come back later. After all, we must have a foothold first.
Fourth: Being a boss, the rich second generation can consider it.
