Excuse me, I want to apply for a job as a tourism management teacher. I will give a trial lecture for 20 minutes. What course should I teach?

I am a student who graduated from the tourism management major in 2008. I think you should teach the basics of tour guides. From the basic courses of tour guides, you can see the cultural heritage of a tourism teacher. At least I think so, unless If you are a graduate in management, then you can only talk about more professional management
