I agree with upstairs. However, based on the landlord's situation, I personally feel that it is of little significance for graduate students to study hotel management. The most useful knowledge of hotel management is in the undergraduate stage, starting from the basic level of the hotel. What you learn in the postgraduate stage is nothing more than the truth in books, which is not practical. Moreover, graduate students do not have internships. After graduation, few hotels will recruit graduates without internship experience. The landlord still thinks it over. Good luck.
