In Chengdu, residents primarily speak Mandarin Chinese and Sichuanese, rather than Cantonese. As the capital of Sichuan Province, Standard Mandarin (Putonghua) is the official language used in government, education, and formal business settings, ensuring that nearly all residents are fluent. However, the local and most commonly spoken language for daily social interaction is Sichuanese, specifically the Chengdu dialect, which is a branch of Southwestern Mandarin. While Sichuanese is linguistically related to Standard Mandarin and shares some mutual intelligibility, it features distinct tones, vocabulary, and expressions. Cantonese is native to the Guangdong province and Hong Kong regions in southern China and is not traditionally spoken in Chengdu.
