Fanling Wai is a village in Fanling, North District, Hong Kong, built by the Pang (彭) Clan. It is composed of a walled village and its two extensions: Ching Wai or Chung Wai (正圍 or 中圍; 'central hamlet') – the only walled hamlet of Fanling Wai and also the first hamlet to be built, Pak Wai (北圍; 'north hamlet'), and Nam Wai (南圍; 'south hamlet').
The Weitou dialect or Wai Tau dialect (Chinese: 圍頭話; Jyutping: wai4 tau4 waa2; lit. 'walled (village) language') is a dialect of Yue Chinese. It forms part of the Guan–Bao (莞寶片; Guǎn bǎo piàn) branch of Yuehai. 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.
