Shaozhou Tuhua

Shaozhou Tuhua (traditional: 韶州土話; simplified: 韶州土话 Sháozhōu Tǔhuà "Shaoguan Tuhua"), also known as Yuebei Tuhua (粤北土话), is an unclassified Chinese variety spoken in northern Guangdong province, China. It is mutually unintelligible with Xiang, Cantonese, and Mandarin.

Classification
Some scholars consider it to be an extension of Ping Chinese (Pinghua) in Guangxi. Others consider it to have a foundation in Song dynasty-era Middle Gan, mixed with Hakka, Cantonese, and Southwestern Mandarin.

Chen (2012) notes that the Shaoguan Tuhua of Shibei (石陂, in Zhenjiang District) shares many similarities with the Hakka of Qujiang District, due to intensive contact.

Sagart (2001) considers the Nanxiong dialect (classified in the Language Atlas of China as a Shaozhou Tuhua dialect) to be most closely related to Hakka. In contrast, Egerod (1983) had proposed a relationship between Nanxiong and Min.

Dialects
Shaozhou Tuhua is also known as Yuebei Tuhua (粤北土话, "Northern Guangxi/Guangdong Tuhua"), and as Shīpóhuà (虱婆话, "Shipo dialect"), Shīnǎhuà (虱乸话, "Shina dialect"), or  Shīpóshēng (虱婆声, "Shipo accent") in its own region. It is also known as Pingdi Yaohua (平地瑶话, "Lowland Yao dialect"), locally Piongtuojo or Piongtoajeu; "Yao" here might be a cultural designation, as only half of the one million speakers are classified as ethnic Yao.
