[2][1] The first edition of the Language Atlas of China places the Hakka dialects spoken in Haifeng and Lufeng[3] into the Xin–Hui cluster (新惠小片; Xīn-Huì xiǎopiàn) of the Yue–Tai subgroup (粤台片; 粵臺片; Yuè-Tái piàn) of Hakka.

[5] Chang Song-hing and Zhuang Chusheng propose that it should be grouped as the Hai–Lu cluster (海陆小片; 海陸小片; Hǎi-Lù xiǎopiàn) of the Mei–Shao subgroup (梅韶片; Méi-Sháo piàn).

[6] In China, the Hailu dialect is spoken in Shanwei, Guangdong, particularly in Haifeng, Lufeng, and Luhe.

[7] In Taiwan, it is spoken in Hsinchu County (Xinfeng, Xinpu, Hukou, Qionglin, Hengshan, Guanxi, Beipu, Baoshan, Emei, and Zhudong), Hsinchu City (Xiangshan and Xinfeng), Taoyuan (mostly in Guanyin, Xinwu, and Yangmei; also pockets in Pingzhen, Zhongli, and Longtan), Hualien County (Ji'an, Shoufeng, Guangfu, Yuli, Ruisui, and Fenglin), and Miaoli County (Toufen, Sanwan, Nanzhuang, Xihu, Houlong, Zaoqiao, Tongxiao, and Tongluo).

[2] In Indonesia, a local variety of Hakka, that is loosely based on the Hailu dialect, is widely spoken in northern West Kalimantan, including Singkawang, Sambas, and Pemangkat.
