Is Nanning a city without traditional cultural characteristics?

I come from Nanning. As far as I know, firstly, Nanning is not a pure northerner who immigrates to the city, but northerners do, but southerners, such as Guangxi natives, are more mobile, so what you should hear is vernacular, Zhuang language (what my family said is Zhuang language), dialects of other counties and cities in Guangxi, and of course, some dialects that are rarely used only in rural areas. Nanning, a city with a large population flow, is the capital after all, so the so-called cultural and traditional features are combined in Guangxi, such as food and so on. If Nanning is a city without dialects, it should speak super-standard Mandarin, then there will be no such thing as Nanning Mandarin ~
