If we adopt the threefold division of Northern Chinese, the form commonly known as ‘Southern Mandarin’ occupies the southern part of Kiangsu, Anhwei south of the river Hwei and north by the Wu boundary, the south-east corner of Hupeh, and all Kiangsi not occupied by Wu or Hakka dialects. The western form covers the southern part of Hupeh, the whole of Hunan except the so-called Hsiang dialect area, and Szechʻwan south of Chengtu, with extensions into the provinces of Kweichow and Yünnan.

Hweichou in southern Anhwei may be a Hsiang dialect or a Wu dialect. Hsiang has no written form apart from standard Chinese.
