Lanyin Mandarin
Lan-Yin Mandarin is a branch of Mandarin Chinese traditionally spoken throughout Gansu province and in the northern part of Ningxia. In recent decades it has expanded into northern Xinjiang. It forms part with Central Plains Mandarin. The name is a compound of the capitals of the two former provinces where it dominates, Lanzhou and Yinchuan, which are also two of its principal subdialects.
Among Chinese Muslims, it was sometimes written in the Arabic alphabet instead of Chinese characters.- Lanzhou dialect 兰州话/蘭州話
