First of all, the most convenient way to make money through your major is of course art students. Students who study dance can go to the gym as dance teachers to earn money. Most dance teachers in gymnasiums don't need to be very professional, because the students' foundation is not solid enough and they don't need too much professional teaching, so it is relatively difficult to be a dance teacher in gymnasiums. At present, dance classes in gymnasiums are arranged around dinner, during which students have more time, and a gym will have multiple dance teachers, so the working hours are more flexible. Candidates who draw pictures can make money by drawing portraits for others online or completing paintings as required.
Secondly, I want to talk about accounting. Students majoring in accounting, if they have obtained an accounting qualification certificate, can put this certificate in some small companies as a listing. You can get about 1000+ every month. An engineer's certificate is also acceptable.
There is another major that can easily make money through its own major, that is, language major. There are many ways for language majors to make money, as follows. First, go to a language learning institution as a part-time teacher or teaching assistant on weekends. This will not only make money, but also accumulate some experience as a teacher. If you want to develop in the direction of language teachers in the future, it is also a good work experience. Second, help others translate documents. Many companies need to translate documents in different languages. Once my Japanese teacher made some extra money in this way. But the problem is that you need someone to introduce you to these jobs. If you have a good relationship with professional teachers, you are more likely to get these job opportunities.
