Bui Xa Communal House, Tien Xa Village, Xuan Mai Commune, Hanoi City

Bui Xa Communal House is located in Bui Xa Village, Xuan Mai Town, Chuong My District. To reach the relic site, visitors can travel from the center of Hanoi City along National Highway 6A to Xuan Mai Town, then turn left to enter Bui Xa Village; from there, it is about 500m to the communal house.

According to the Ngoc pha and legends among the villagers, Bui Xa Communal House is where the three Great Kings, the Tan Vien Son Thanh, are worshipped from the reign of King Due Vuong. These are cultural heroes who helped the king fight invaders and defend the country, taught the people to raise silkworms and weave cloth, and develop agriculture. Therefore, through the Dinh, Le, Ly, and Tran dynasties, they were all conferred the title of Superior Blessed Deity.

According to the village elders, in ancient times Bui Xa Communal House was a large communal house in the region with all components: Nghi Mon ceremonial gate, Ta Huu Mac left and right wings, Thieu Huong incense burning house, Dai Bai main hall, and Hau Cung rear sanctuary. The overall architectural layout of the relic is in the shape of the Chinese character đinh. Dai Bai is a building consisting of 3 bays, 2 sloping roofs, covered with ri tiles, with closed gable walls. The ridge is decorated with a dinh-shaped edge, and two pillars are built at both ends of the ridge. Inside, the roof trusses are uniformly made in the keo ke qua giang style. This Dai Bai structure is a product of the restoration and embellishment during the Duy Tan period (1907-1915). In the central bay of Dai Bai, an incense altar is arranged, with a set of eight treasures on both sides, and above it hangs a horizontal plaque inscribed with four Chinese characters Thanh cung van tue.

Passing through Dai Bai, one reaches the Hau Cung, which has 2 bays in the style of closed gable walls with 2 sloping roofs covered with old ri tiles; the front has three doors, the middle door is built half-height while the two side doors are used for passage. The roof trusses are made in the van me, con me style; the panels here are carved with a phoenix holding a book, below are cloud patterns, and the gable walls are painted with two dragons facing a yin-yang symbol. On the bodies of the main columns in the rear sanctuary are hung couplets praising the merits of the village tutelary god.

The annual festival of Bui Xa Village is held on the 12th, 13th, 14th, and 15th days of the first lunar month, with offerings to the village tutelary god including a yellow-feathered rooster with no white feathers, along with bananas, oan cakes, and fruits; the ceremonial rooster must be clean and pure to be offered to the tutelary god.

The communal house was ranked as a historical-cultural relic by the People's Committee of Ha Tay Province in 2005.
