What about graduating from graduate school and going to a university to become a teacher?

I think it’s okay. Teachers’ salary prospects are very good now, and more importantly, they can teach and educate people. Generally, new employees from universities are priced at this price, but if you have a graduate degree, you are fully qualified to apply for a salary increase. It may be that you did not mention this requirement during the interview, or your attitude was too low. If If you still want to stay, just work hard during this period, make some achievements, and then talk to your boss about your performance. If it still doesn't work, then there is no need to stay any longer. Well, you can find a job better than this anywhere. Since you can graduate from a master's degree, your value is definitely more than this.
