Hainanese in the context of "Mutually unintelligible"

Min is a broad group of Sinitic languages with about 75 million native speakers. These languages are spoken in China in a region centered on modern Fujian Province, stretching from Southern Zhejiang to Eastern Guangdong, as well as on Hainan Island and the neighbouring Leizhou Peninsula. Min varieties are also spoken in Taiwan, and by a large international diaspora, particularly in Southeast Asia. The name Min is shared with the Min River in Fujian, and is also the abbreviated name of Fujian Province. Min languages are not mutually intelligible with one another nor with other varieties of Chinese.

The most widely spoken variety of Min outside of China is Hokkien, a variety of Southern Min which has its origin in Southern Fujian. Amoy Hokkien is the prestige dialect of Hokkien in Fujian, while a majority of Taiwanese people speak a dialect called Taiwanese Hokkien or simply Taiwanese. The majority of Chinese Singaporeans, Chinese Malaysians, Chinese Filipinos, Chinese Indonesians, Chinese Thais, and Chinese Cambodians are of Southern Min-speaking background (particularly Hokkien and Teochew), although some of these communities are shifting to national or regional languages. Communities speaking Eastern Min, Pu-Xian Min, Haklau Min, Leizhou Min, and Hainanese can also be found in parts of the Chinese diaspora, such as in Malaysia, Singapore, and Indonesia.

Leizhou or Luichew Min (simplified Chinese: 雷州话; traditional Chinese: 雷州話; pinyin: Léizhōuhuà, [lěɪʈʂóʊ xwâ]) is a branch of Min Chinese spoken in Leizhou city, Xuwen County, Mazhang District, most parts of Suixi County and also spoken inside of the linguistically diverse Xiashan District. In the classification of Yuan Jiahua, it was included in the Southern Min group, though it has low intelligibility with other Southern Min varieties. 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 Hainanese in a Qiong–Lei group.
