Tang Tsing Lok Ancestral Hall, Ancestral hall in Yuen Long District, Hong Kong.

Tang Tsing Lok Ancestral Hall is a family shrine in Yuen Long District organized into three connected halls separated by two interior courtyards. Wooden beams are intricately carved, and the roof ridges display ceramic figures that reflect traditional craftsmanship of the era.

Built around 1490 in the early Ming dynasty, the hall honours Tang Tsing Lok, the 17th-generation ancestor of the Kam Tin Tang. It was repaired in 1794, the 59th year of the Qianlong reign, and restored again in 1981 together with the adjacent Tang Chun Suen Hall. It is now a Grade I historic building.

Each year at the Lantern Festival, Tang clan members gather here for a ancestral rite and light lanterns for boys born in the previous year. The boys' names are first entered in a register of male births before being recorded in the clan genealogy. A screen inside the main door was opened only for visiting officials.

The building sits in a residential neighborhood reachable on foot from central Yuen Long, with bus stops nearby for those traveling from farther away. Visitors should dress respectfully and keep voices low, as the site is still used for family ceremonies and private rituals.

The screen inside the main door stays closed except for visits by high officials and notables. Above, the "Si Cheng Tang" plaque is said to have been begun by Chu Pengling, a 1780 jinshi, who died after finishing two characters, leaving the third to another hand; records show Chu actually died in 1825, so the tale is likely false.
