Ba-Shu Chinese
Ba-Shu Chinese, or Old Sichuanese, is an extinct Sinitic language formerly spoken in what is now Sichuan and Chongqing, China. This language is first attested in Fangyan during the Western Han dynasty and represents one of the earliest splits from Old Chinese or Early Middle Chinese. It became extinct during the Ming dynasty, when it was supplanted by Southwestern Mandarin after settlement by people from other parts of China.
Phonological aspects of Ba-Shu Chinese are preserved in the Minjiang dialect of Sichuanese Mandarin and there is debate on whether it is a variant of Southwestern Mandarin or a modern day descendant of Ba-Shu.
