Due to its primary usage in isolated regions where communication is limited to the local area, Hakka has developed numerous varieties or dialects, spoken in different provinces, such as Guangdong, Guangxi, Hainan, Fujian, Sichuan, Hunan, Jiangxi, Guizhou, as well as in Taiwan, Singapore, Malaysia, Thailand and Indonesia.

It is commonly believed that Hakka people have their origins in several episodes of migration from northern China into southern China during periods of war and civil unrest[10] dating back as far as the end of Western Jin.

[11] The forebears of the Hakka came from present-day Central Plains provinces of Henan and Shaanxi, and brought with them features of Chinese varieties spoken in those areas during that time.

Laurent Sagart (2002)[12] considers Hakka and southern Gan Chinese to be sister dialects that descended from a single common ancestral language (Proto-Southern Gan) spoken in central Jiangxi during the Song Dynasty.

[citation needed] Today, most She people in Fujian and Zhejiang speak She, which is closely related to Hakka.

Meixian is surrounded by the counties of Pingyuan, Dabu, Jiaoling, Xingning, Wuhua, and Fengshun.

Moreover, there is evidence of the retention of an earlier Hakka tone system in the dialects of Haifeng and Lufeng, situated in coastal southeastern Guangdong province.

Sixian speakers come from Jiaying Prefecture, mainly from the four counties of Chengxiang (now Meixian District), Zhengping (now Jiaoling), Xingning and Pingyuan.

Most dialects of Taiwanese Hakka, except Sixian and Dabu, preserved postalveolar consonants ([tʃ], [tʃʰ], [ʃ] and [ʒ]), which are uncommon in other southern Chinese varieties.

Ethnologue reports the dialects of Hakka as being Yue-Tai (Meixian, Wuhua, Raoping, Taiwan Kejia: Meizhou above), Yuezhong (Central Guangdong), Huizhou, Yuebei (Northern Guangdong), Tingzhou (Min-Ke), Ning-Long (Longnan), Yugui, and Tonggu.

Dialects of Hakka have been written in a number of Latin orthographies, largely for religious purposes, since at least the mid-19th century.

It broadcast nine hours of Hakka Chinese programs every day through shortwave radio and online radio, targeting countries and regions where Hakka people gather, such as Japan, Indonesia, Mauritius, Reunion Island, Australia, Hong Kong and Taiwan.

In 2005, Meixian Radio and Television Station (梅縣廣播電視臺) was reorganized after the separation of the National Cultural System Reform Bureau.

The channel can be watched in Meizhou and surrounding area with an audience of over 4 million people.

In 2019, Shenzhou Easy Radio (神州之聲) added a Hakka Chinese radio break which broadcasts to the southeast coast of Mainland China, Taiwan, Southeast Asia, the South Pacific and Japan.

On Radio The Greater Bay (大灣區之聲), Sihai Kejia Channel has also joined.
