It is named afterChengdu, the capital city ofSichuan, andChongqing, which was under the administration of the province of Sichuan from 1954 to 1997. It is spoken mainly in northern and eastern Sichuan, the northeastern part of theChengdu Plain, several cities or counties in southwestern Sichuan (Panzhihua,Dechang,Yanyuan,Huili andNingnan), southernShaanxi and westernHubei.^[1][2]

This uniform dialect is formed after the great migration movement inMing andQing dynasty, and is greatly influenced by theChinese varieties ofMandarin the immigrants spoke from Hubei,Xiang andGan. So it keeps fewer characteristics of Sichuan's originalBa-Shu Chinese than other Sichuanese dialects, such asMinjiang dialect.

The Chengdu-Chongqing dialect is mutually intelligible with dialects spoken in its satellite districts such Sichuan. But, as all public schools and most broadcast communication in urban Chongqing use Mandarin exclusively, nearly all speakers of the dialect are good at Chongqing dialect and Mandarin. Owing to migration within China, traditional Chongqing dialect is getting similar to Mandarin, many residents of the city cannot speak the local dialect but can usually understand it, and get fluent to it after a few months or years in the area.^[4]

With Chinese government declared movement to Chongqing during the World War II, Chongqing became the Provisional capital of the republic of China,^[6] when migration boost the population of the city. Chongqing dialect mixes the merits of various local dialects, with wits and humor, gains popularity with its users.

About one third of Sichuan dialects have a special entering tone, with a relatively independent set of finals, e.g.:[iæ],[uæ],[ʊ],[ɘ],[ɐ],[iɐ],[uɐ],[ɔ],[yʊ],[yɵ], etc. These vowels keep the throat tight, ensuring the muscles of the larynx and oral cavity stay tense during pronunciation, so that the entire syllable exhibits a rough and tight state.^[9]

Affected by Mandarin for a long time, literary and colloquial readings appear in the Chongqing-Chengdu dialect. Colloquial readings are usually the inherent reading style from the ancient Sichuan dialect, mainly appearing in high-frequency everyday communication; literary readings are close to modern Mandarin, normally appearing in written language. The literary and colloquial readings have been developing in the recent decades. However, affected bythe promotion of Mandarin Chinese by the Chinese government, literary readings are becoming dominant, and some pronunciations have the tendency to disappear.^[11] Literary and colloquial readings of Chinese characters in Chengdu are shown below.^[12] Note: the table is only based on 《成都语音的初步研究》in 1958, the changes of Chengdu dialect in recent years are not considered:
