Thanh Diem Communal House

Location: The communal house is located in Thong Nhat village, Tho Xuan commune, Dan Phuong district, Hanoi city.

Worshipped Figure: The communal house worships the village guardian deity Nguu Lan Dai Vuong.

Divine biography and merits: He was born on the 6th day of the 2nd month of the Year of the Ox (At Suu) (at Thanh Tra) into a virtuous family; from an early age he showed intelligence and talent in both civil and military strategy. Under the Le kings, he joined the army to fight the enemy and was appointed Marshal Grand Commander, commanding both naval and land forces. He directly commanded the defeat of the Mac army, pursued Mac Mau Hop out of Thang Long, and was granted by the king the title Marshal Grand Commander of the Ministry of Justice. He passed away on the 4th day of the 11th month in a pink cloud and was conferred by the king as an upper-grade deity.

2. Distinctive features of architecture, art, and relics. The communal house has a traditional architectural layout including: Nghi Mon (ceremonial gate), Dai Bai (main hall), Ong Muong (tube corridor), and Hau Cung (rear sanctuary).

Ceremonial gate: Majestic with pillar architecture, tops decorated with four converging phoenixes, tiger-talisman panels, and the four sacred creatures. Two sides have reliefs of war horses, war elephants, and guards, bearing strong martial imprints.

Dai Bai Hall and Ong Muong: Dai Bai consists of 5 bays and 2 side bays, with a wooden frame built in the sturdy "bao tron dong ben" style. The artistic highlight lies in the relics arranged there dating from the 20th century, such as: the horizontal plaque "Thanh cung van tue", a system of finely carved pierced lattice doors, a wooden incense altar carved with two dragons flanking the moon, tiger-talisman faces, and two rows of eight weapons.

Rear sanctuary: The most sacred place consists of 3 longitudinal bays, preserving the statue of the village guardian deity, the dragon throne, and the memorial tablet. These are treasures dating from the 19th century with extremely delicate carving techniques by ancient artisans.

3. Distinctive traditional festival

Main festival days: Every year, villagers hold meetings and ceremonies at the communal house on important occasions: the full moon of the first lunar month, the 5th day of the third lunar month (commemorating his birth), the 13th day of the eighth lunar month, and the 4th day of the eleventh lunar month (commemorating his transformation).

Meaning of the festival: During these days, villagers perform solemn rituals to express gratitude for the merits of the village guardian deity. At the same time, they organize vibrant community cultural and artistic activities, creating space for people to "immerse themselves," contributing to strengthening neighborhood bonds and building great solidarity.
