King Law Ka Shuk, Ancestral hall in Tai Po Tau, Hong Kong.

King Law Ka Shuk is a three-hall, two-courtyard ancestral hall and study hall in Tai Po Tau Tsuen, Tai Po, covering 349.69 square metres. Two drum terraces with granite columns stand before the entrance, and the main ridge and wall friezes carry geometric plaster mouldings. The stone plaque above the door bears the hall's name in the calligraphy of Tang Yi-nga (1884–1954).

The Tang clan built this ancestral hall in the early 18th century after arriving in the area, having first migrated here during the 13th century from Kam Tin in Yuen Long. The hall represents the family's long-standing presence and roots in the region.

The hall is still used for clan meetings and traditional festival functions by the Tai Po Tau Tang. The name honours Tang King Law, the tenth-generation ancestor revered as the first of the Lau Kwong Tong branch. The main chamber's "Lau Kwong Tong" plaque was written by the revolutionary Hu Hanmin.

The building still hosts clan gatherings and traditional ceremonies where family groups meet and celebrate together. Access is possible but visitors should respect the ongoing use of the space as an active community gathering place.

Before restoration began, the Antiquities and Monuments Office commissioned the Guangdong Provincial Institute of Cultural Relics and Archaeology to survey the building; experts spent a month on site producing measured drawings and a conservation plan. The 1998–2001 project won a UNESCO Asia-Pacific Award of Merit in 2001.
