Man Ancestral Hall, San Tin, Ancestral hall in San Tin, Hong Kong.

Man Ancestral Hall (Dun Yu Tong) is a two-hall ancestral hall in Fan Tin Village, San Tin, built in 1444. The inner hall holds wooden ancestral tablets, while the central hall displays a portrait of Wen Tianxiang and seven spirit tablets for non-Man martyrs who defended the village. Couplets read "望煙傳世澤" and "正氣著家聲".

This ancestral hall was built as a memorial site for the Man family and has served since its founding as a center for honoring ancestors and family devotion. The structure became a gathering point for clan activities and is now protected as a Grade I historic building.

The hall is still used for clan weddings, lantern-lighting ceremonies, jiao rites, group greetings and the spring and autumn sacrifices. Its couplet "望煙傳世澤" recalls ancestor Man Ying-lin, who built a lookout tower on Fenghuang Hill in Shenzhen to relieve the poor; the lower line "正氣著家聲" refers to Wen Tianxiang.

The hall is still used by the Man clan for weddings, lantern-lighting, jiao rites, clan gatherings and the spring and autumn sacrifices, so access may be limited during those events. A kindergarten, Dun Yu Kindergarten, operates in an annex building in the courtyard, so expect children and staff on weekdays.

The hall houses carefully maintained family genealogies that link current Man clan members to their ancestors through documented lineages spanning many generations. These records are invaluable to family members seeking to understand their roots and family relationships across centuries.
