Language Atlas of China in the context of "Leizhou Min"

Hainanese or Hainamese (Hainan Romanised: Hái-nâm-oe, Hainanese Pinyin: Hhai3 nam2 ue1, simplified Chinese: 海南话; traditional Chinese: 海南話; pinyin: Hǎinánhuà), also known as Kengbun/Kengvun (simplified Chinese: 琼文话; traditional Chinese: 瓊文話), Keng language (琼语; 瓊語) or Hainam Min (海南闽语; 海南閩語) is a language of Min Chinese spoken in the island of Hainan and regional overseas Chinese communities in Thailand especially.

In the classification by Yuan Jiahua, it was added to the Southern Min group by Him despite being mutually unintelligible with Southern Min varieties such as Hokkien and Teochew. In the classification of Li Rong, used by the Language Atlas of China, it was treated as a separate Min subgroup. Hou Jingyi combined it with Leizhou Min, spoken on the Leizhou Peninsula, in a Qiong–Lei group. "Hainanese" is also used for the language of the Li people living in Hainan, but generally refers to Min varieties spoken in Hainan.

Northeastern Mandarin (simplified Chinese: 东北话; traditional Chinese: 東北話; pinyin: Dōngběihuà; lit. 'Northeast Speech' or 东北官话/東北官話 Dōngběiguānhuà "Northeast Mandarin") is the subgroup of Mandarin Chinese spoken in Northeast China with the exception of the Liaodong Peninsula and few enclaves along Amur and Ussuri rivers. The classification of Northeastern Mandarin as a separate dialect group from Beijing Mandarin was first proposed by Li Rong, author of the Language Atlas of China, in 1989. However, many researchers do not accept the distinction.
