The area's winding shores, hilly land, and islands, as well as its distance from administrative centres, made the territory of Hong Kong an excellent hideout for pirates.[citation needed] Popularly known as Kam Tin, from the name of the area, it is home to about 400 descendants of the Tang Clan, who built the village back in the 17th century.As a family stronghold, Kat Hing Wai has served the Tangs well through the centuries, protecting the residents against bandits, rival clans, and wild tigers.Tsang Tai Uk (曾大屋), also known as Shan Ha Wai (山下圍),[3] is another well-known Hakka walled village in Hong Kong, and one of the best preserved.Characterized by its magnificent moat and landscape setting, the walled village is the core of the Liu clan, of which ancestors came originally from Fujian during the Yuan dynasty (1271–1368).
