Unlike Sichuanese (or Sichuanese Mandarin), which is a native language spoken in the Sichuan region and differs greatly from Standard Mandarin, Sichuanese Standard Mandarin (or Chuanpu) arose after the Popularize Mandarin Policy was implemented by the Chinese government in 1956 and is in fact Standard Mandarin with a Sichuanese accent and some elements of Sichuanese vocabulary and grammar. In this view, Chuanpu is, to a certain degree, similar to Taiwanese Mandarin and Singaporean Mandarin.
Chuanpu is spoken by Sichuanese people who are required to communicate with people from outside of Sichuan and Chongqing, but who cannot speak authentic Standard Mandarin. Chuanpu is also often used humorously among local people who find it funny. Due to its humorous effect, Chuanpu is occasionally used in local television, broadcasting and popular music, with good results. Chuanpu Waichang (川普歪唱), the music sung in Chuanpu, is very popular in Sichuan and Chongqing and is usually adapted from famous songs.
