Kat Hing Wai (吉慶圍) is a well known Punti walled village in the Yuen Long District of Hong Kong. It is often mistakenly believed to be Hakka, whose people have similar traditions. However the Punti people were from Southern China and the first to settle in Hong Kong. Kat Hing Wai's residents speak the Weitou dialect, a Yue dialect, rather than Hakka. Popularly known as Kam Tin, from the name of the area, the village is home to about 400 descendants of the Tang Clan, one of the "Five Great Clans" of the territory that built the village in the 17th century.
