What dialects are there in Gansu?

The initials of Gansu dialect are quite different from those of Mandarin, which are mainly manifested in the following points: zero initials are less than those of Mandarin.

All four sounds in Mandarin are zero initials. Although there is always some friction at the beginning of these zero initials in actual pronunciation, this kind of fricative sound is slight, sometimes obvious, sometimes not obvious, so the initial position is a "virtual position".

Gansu dialect reads some zero initials of Putonghua as words with consonants. The general situation is as follows:

(1) In many places, the initial n or ng is added before the initial zero. For example, Linxia, Pingliang, Qingyang and other places in Gansu Province have added the words "An", "Ai", "Ao", "En" and "Ou" with N initials, while Dingxi, Tianshui and Wudu have added ng initials. There are other special cases, for example, people in Gangu read the word "love" and "forehead" with the initial g, and people in Lanzhou read the word "hunger" with the initial v.

(2) Shut up and shout out initials, such as "I", "Wen", "Wu", "crooked", "forgotten" and "Weng". In almost all areas of Gansu province, the sound at the beginning of syllables is pronounced "V".
