To Ancestral Hall, Tuen Tsz Wai, Ancestral hall in Tuen Tsz Wai, Hong Kong.

To Ancestral Hall, also called Wu Liu Tang, stands between Tuen Tsz Wai and San Hing Tsuen in Lam Tei, Tuen Mun. It is a three-bay, three-hall building with two courtyards, built on a granite base with blue-brick walls and a drum platform under the front porch. The hall is now vacant.

The original building was completed in 1718 during the Kangxi period of the Qing Dynasty. Later recognition as a Grade I historic building confirmed the importance of its architectural features and place in regional history.

The hall is also known as Wu Liu Tang, a name it shares with the Wu Liu Primary School that used its rooms before 1954. The To clan built it as the first of two ancestral halls in Tuen Mun, and a stone inscription inside records its 1925 renovation.

The hall is located in northern Tuen Mun District and can be reached via Castle Peak Road or nearby Light Rail stations. Plan your visit during daylight hours when the spaces are most accessible to view.

The To clan believed the hall's position facing Fu Tei, the ancestral grave site of the Ping Shan Tang clan, created a "dragon-tiger" confrontation harmful to feng shui. They built Sam Sing Kung beside the hall, enshrining Hung Shing, the God of Wealth and Yeung Hau Wong to suppress the "tiger".
