Is there a big difference between Neijiang dialect and Chengdu dialect?

Neijiang dialect just doesn't sound like Chengdu dialect, but it has the tongue sounds of zh, ch and sh, but they are all Sichuan dialects with little difference in tone.

Sichuan dialect belongs to southwest mandarin, also known as Bashu dialect. Today's Sichuan dialect was formed in the great migration movement of "Huguang filling Sichuan" during the Kangxi period of Qing Dynasty, and it was formed by the gradual evolution and integration of Shu dialect popular in Sichuan before the Ming Dynasty and immigrant dialects in Huguang, Guangdong and Jiangxi.

Chengdu dialect is the standard pronunciation of Sichuan opera and various folk arts. At the same time, due to the high degree of internal communication in Sichuan, taking Dazhou dialect as an example, the communication between dialect areas is not barrier-free, and Sichuan dialect is a general term, so Sichuan dialect itself has no standard pronunciation.
