I'm a girl, and my major in tourism hotel management and IT has a better job prospect after graduation.

IT, of course. Let me tell you this, hotel management sounds very nice. In fact, when you go to a hotel, you will find that some directors or managers are not as educated as you, but they have been working for a long time, you know? Moreover, the hotel industry is not short of high-level, only some low-level workers, waiters and the like, or at most supervisors.
