 The new script was popular in the Jianchuan area, but was rejected in the more economically advanced area of Dali, which also had the largest number of speakers, albeit living alongside a large number of speakers of Chinese.The script was revised extensively in 1993 to define two variants, representing Jianchuan and Dali respectively, and has since been more widely used.The retroflex initials "zh", "ch", "sh" and "r" are used only in recent loanwords from Standard Chinese or for other Bai varieties.
