Sichuan dialect is the main Chinese language popular in Sichuan, Chongqing (Bashu area) and neighboring provinces [1], including the Southwest Mandarin which originated from the ancient Shu dialect. [2] Sichuan dialect has about 16 million users, which is second only to Japanese and more than German. [3] Today, Sichuan dialect was formed during the Great Migration Movement of "Huguang filling Sichuan" during the Kangxi period of the Qing Dynasty. It was formed by the gradual evolution and integration of Shu dialect popular in Sichuan before the Ming Dynasty and immigrant dialects from Huguang, Guangdong and Jiangxi. Chengdu dialect is the standard pronunciation of Sichuan Opera and all kinds of Quyi. At the same time, Sichuan dialect has no standard pronunciation because of its high internal interoperability and barrier-free communication among dialect areas.
