Thank you for your love of Chifeng. I am from Chifeng, and now I happen to work in Hohhot. Colleagues will know that I am from Chifeng when they listen to me for a few words. There is nothing wrong with speaking Chifeng dialect well. The key is to have a language environment and make friends with several Chifeng people. Chifeng dialect is really not standard. Compared with Mandarin, it's a little thick, so I can't open my chin. The sound of "O" is always pronounced as "E". I think you can learn Mandarin.
