Xi' an is a quaint big city, and it may be because it is an ancient city ideologically. It always feels a bit pedantic and wants a good development, but when it comes to struggle, because of its size and geographical location, it has more opportunities than Guiyang at present. Speaking of living, Guiyang is a livable city in China, with high comfort. Don't think too much about the problem of xenophobia. It's the same everywhere. China people have their own characteristics, more or less. I am from Guiyang myself. I think Xi' an people are very unfriendly and I don't know what others think of our Guiyang.
