Why is Lorraine's accent so strange?

Luoning's accent is a mixture of Shaanxi dialect and Shanxi dialect brought by immigrants and refugees in Ming Dynasty. The reasons for the formation of Luoning dialect are relatively simple, but its formation process is long and complicated. There are "water and soil theory", "environment theory", "region theory", "character theory" and so on. As the saying goes, "soil and water support one person", the social practice of a group of people living together will form a unique national and local cultural characteristics. Writing is a culture, and language is also a culture. The author believes that the formation of language is not only influenced by a place's unique regional environment and humanistic environment, but also has a great relationship with the administrative divisions and organizational system in this place's history. Because since you are under the jurisdiction of this administrative region, there will be a lot of contacts and exchanges between people, which will inevitably influence each other and eventually form a unique "dialect" in a region.
