The employment situation is very good. There are more jobs in Spanish, but Portuguese is better than few people. There are few schools offering this major in China, and the salary level in Portuguese is slightly higher. So now the employment prospects of these two languages are very good, and graduates have more choices when looking for jobs. But it's hard to say after four years, because now more and more schools offer these two majors, and more and more people learn them, but language itself is a relatively restrictive major. If you learn a language, you'd better learn something else in your spare time to broaden your knowledge. Tianwai's junior Portuguese major went to Lisbon University in Portugal for one year, which was a good opportunity and also had the opportunity to take the postgraduate entrance examination.
But you still have to decide for yourself. After all, no one can predict what will happen in four years. Good luck!
