Descendants of the local Tang clan originated from Jiangxi Province in mainland China and moved to settle in Kam Tin, and later branching out into Lung Yeuk Tau, Ha Tsuen, Tai Po and Ping Shan amongst other areas.

Due to the construction of the Kowloon-Canton Railway at the beginning of the 20th century, the village was separated into Shui Wai and Tai Po Tau.

Apart from being a place for ancestral worship, it was used as a shuk (study hall) for preparing clan members for important imperial examinations.

There are three halls and two courtyards at King Law Ka Shuk, which is a traditional Chinese building with a functional design and elegant ornamental features.

Geometric plaster mouldings can be found on the roof ridges and wall friezes while for the internal eave boards, patterns of leafy and motifs are used.

Tang Yung-Kang is also noted for being the Hanlin Yuan Shue Kat Sz (Imperial examination scholar) in the tenth year of the reign of the Tongzhi Emperor (1871) during the Qing dynasty.

Other participants included professional conservators from Hong Kong, mainland China and the UK, as well as the villagers from Tai Po Tau Tsuen.

Some improvement works like re-laying the front courtyard as well as the provision of lighting and power supply for some night time functions or celebrations were also conducted.

Among the rituals of restoration of traditional Chinese buildings, the raising of the ridge purlin, the main roof support beam, is the most significant.
