It is spoken by older generations in Luohu and Futian districts in Shenzhen, and by those in the New Territories, Hong Kong.
The Weitou dialect can be heard in Hong Kong TV dramas and movies, and is usually used to depict characters who come from walled villages.
For example, in the 1992 movie Now You See Love, Now You Don't, the chief character, played by Chow Yun-fat who himself grew up in Lamma Island, consistently speaks the Weitou dialect.
In a more general sense, Weitouhua can refer to any variety of Chinese spoken in the villages of Hong Kong, including Hakka and rural Yue dialects.
Zhang & Zhuang (2003:21-4) records the phonological systems of three varieties of the Weitou dialect spoken in Hong Kong.
