Any Stories Where Hogwarts Comes to the East to Practice Immortality?

There are already so many stories about Eastern exchange students going to Hogwarts. I want stories about Western exchange students coming to the East! Something where they're in a country they're unfamiliar with, have their worldview shattered and rebuilt step by step, then happily decide to join in. I haven't come across one yet. Please recommend some!
