An overview of Zigong dialect

Zigong dialect is the most difficult to learn in Sichuan, and I have never heard of any foreigner who can speak Zigong dialect fluently. Personally, I feel that the pronunciation of flat tongue and rolled tongue is very close to that of Mandarin, while the edge sound and nasal sound are very close to Sichuan dialect, so it is very easy for anyone in Zigong to speak Mandarin. If foreigners want to learn Zigong dialect, northerners may be more eager to learn it, because the flat roll of the tip of the tongue is more difficult to master than the tone of articulation; At the same time, Zigong dialect, which is influenced by the southern dialect, gives people the overall feeling of being "southern". It is difficult for northerners to say that smell, and even dialects are very different from those in the north. Generally speaking, Zigong dialect is really difficult to learn.
