The closest I got to Guanzhou proper was Hong Kong, and that only to deal with visa issues before that avenue was closed. I've never lived anywhere with Yue as the dominant language. I lived briefly in a city (Xiamen) where Minnan was a huge influence, and lived for two years in a city (Jiujiang) where Gan was a major dialect, but most of my actual living here was done in Wuhan where a form of Mandarin (albeit a very loose form of it!) is the dominant dialect.
