You should promote culture and spiritualism, like Buddhism and temples...I believe I have that right.
You should tell the ways that it is unspoiled by modern society (I hope). I believe that you have an area similar to Tibet but you haven't been taken over an assimilated by China. I would stress old customs that you have.
I've never been to Tibet, so I hope I am right about my answers. I would talk about Tibet's past and make it sound romantic and a good place to get in touch with religion and show photos of old buildings and monestaries and regular people who are interesting. pictures of small children always help.
