Graduated from junior high school, now 18. I have been working as a helper in the hotel kitchen for almost three years.

If you like to be a chef, it is natural to learn this skill well, so you don't have to think about it. Just go back to school and study in a junior college, because in today's society, a junior college diploma doesn't have much effect. Employers will of course need to look at the relevant diploma when recruiting personnel, but what is more important is personal ability. If you have a grade certificate or a professional qualification certificate of a related major, the diploma is irrelevant.

If you don't like this line of work and don't have other skills you like, then you can consider going back to school to study in a junior college and then studying in an undergraduate course to broaden your horizons and increase your knowledge. After all, now this society is an era of knowledge. When studying, you can consider your own related industries.
