Xiao'erjing or Xiao'erjin or Xiaor jin or in its shortened form, Xiaojing, literally meaning "children's script" or "minor script" (cf. "original script" referring to the original Perso-Arabic script, ), is the practice of writing Sinitic languages such as Mandarin (especially the Lanyin, Zhongyuan and Northeastern dialects) or the Dungan language in the Perso-Arabic Script. It is used on occasion by many ethnic minorities who adhere to the Islamic faith in China (mostly the Hui, but also the Dongxiang, and the Salar), and formerly by their Dungan descendants in Central Asia. Soviet writing reforms forced the Dungan to replace Xiao'erjing with a Roman alphabet and later a Cyrillic alphabet, which they continue to use up until today.
