2. It is not recommended to change the project later. Engineering is a popular major in Grade 80, and it will definitely cost a lot of money to learn. From the beginning, I decided that the engineering society saved a lot of gold coins. As for local tyrants, it doesn't matter. They are all masters of money, so it is no problem to study engineering in the future. As for other majors, just choose one of forging and jewelry processing. There is not much difference between the two majors. You can choose either one.
