How many kinds of Shanxi accents are there?

Shanxi accent is basically understandable. As long as you can understand Mandarin, there are great differences in Taiyuan dialect, Datong dialect, Yuncheng dialect and Changzhi dialect. They are almost the same, understandably. For those who don't know foreigners, it's Gujiao dialect, near Lvliang. If you speak fast, you can hardly understand them.
