I think you can find an internship experience as an art teacher first to see if you really like it. If you really like the profession of art teacher, do it. Now there are so many channels, online and offline can be done at the same time. You can set up paid courses on software such as Tencent Classroom, or you can set up an entire community on the official WeChat account. This kind of passive income is also considerable. And I think there are many ways of education in this industry, such as Wanmen University. If it is done well, it is a real cow.
Besides, interior design has passed the stage of attracting gold. If you don't take the postgraduate entrance examination, it will be particularly difficult. Moreover, if you do something wrong in the construction process, such as the ceiling, the designer will pay compensation. If you have less work experience, you will take a single job, do something wrong ... and pay for it. Of course, if you want to enter a design institute and earn five or six figures in each job, then take the postgraduate entrance examination and get into a good university without being discriminated against by the school.
No matter which way you take, you should work hard and think clearly about what you want.
