I want to be a graduate student of tourism management in Beijing.

This has many research directions, but it may not be called this name. In fact, most graduate students majoring in tourism management have hotel orientation, but their names are different, which has no influence on what you study, future development and work. So you only need to consider having a tourism department, but there are too many colleges and universities offering tourism departments now, so you should make a good choice. Beijing is better than Peking University and North Second Foreign University, and everything else is newly established. Teachers are not good at anything. I suggest not to take the exam, otherwise employment will be a problem. Or you can choose Tianjin Nankai. The management of tourist hotels in Nankai is the earliest in China, and it is better in all aspects.

In addition to public courses, there are generally two subjects in the exam, an introduction to tourism and tourism economy, which are easier to review. There are no requirements for university majors and work experience. If the previous major and work experience are wrong or wrong, the only thing that may be relevant is the second interview, which may be asked, but it has little to do with whether you are admitted or not, mainly depending on the score.

I don't know your specific situation, you can ask more specifically.
