Dan Nhiem Communal House, Dan Nhiem Village, Thuong Tin Commune, Hanoi City

According to the Than pha compiled by Grand Secretary of the Hanlin Academy Nguyen Binh in the first year of Hong Phuc (1572) and respectfully copied by Nguyen Hien, Manager of the Hundred Deities Hall and Hung Linh Junior Minister, which is currently kept at the communal house, Dan Nhiem Communal House worships Quy Minh Dai Vuong.

Legend has it that in the reign of the 18th Hung King, there was a clan head named Tuan Xuong, whose wife was Pham Thi Huong. The family was wealthy and virtuous, devoted to doing good, so they were loved by the local people. On the 10th day of the first lunar month in the Year of the Dragon, they gave birth to a son with a handsome appearance, intelligent and talented, and named him Quy Minh. As he grew, Quy Minh became increasingly skilled in both literature and martial arts and was filial to his parents.

At that time, invaders came to invade Van Lang, and the Hung King issued an edict calling on talented people to help the country. Hearing this, Quy Minh asked to go fight the enemy. The king appointed him Commander-in-Chief of the army. He led campaigns, defeating east and pacifying north, achieving many victories. When he and the main army reached the territory of Dan Nhiem commune, Boi Khe canton, Thanh Oai district, he let the soldiers rest. Seeing that this land had beautiful spiritual energy, he set up a military camp and left one hundred quan of money for the local people to build a living shrine, and ordered soldiers to reclaim 50 mau of rice fields to distribute to the poor, called the Quan field. After he died, the villagers of Dan Nhiem honored Quy Minh Dai Vuong as the village's tutelary god.

The communal house stands on a strip of land along the bank of the Nhue River. From the outside in, Dan Nhiem Communal House consists of the Nghi Mon, Dai Bai, and Hau Cung. The Dai Bai building is like a large boat, 15.7 m long, with four gracefully curved, soaring roof corners. The roof is decorated with a kìm whose mouth holds the two ends of the ridge, and whose tail curves like a wheel of reincarnation. In the middle of the ridge, a statue group of two dragons flanking the sun was built, adding to the relic's majestic beauty. The Dai Bai is divided into five bays with four rows of round wooden columns. The roof trusses are made in the chong ruong style, and the side trusses are panels carved elaborately and vividly. Especially, the four panels in the two trusses of the central bay are carved and decorated with sacred creatures depicting the scene of 'four sacred creatures turning the bowl' or the theme of 'fish and dragon sporting in water'. The backs of the panels are embossed with stylized flowers and leaves such as apricot, bamboo, and pine transformed into dragons. On the bodies and ends of the side beams, artisans also decorated motifs of flowers, leaves, dragon flowers, phoenix-tree leaves, and lat leaves with soft, graceful lines. Past the Dai Bai is the Hau Cung. This is a longitudinal building, whose trusses are made in the keo cau qua giang style, tending toward smooth planing and close joining. Based on the architectural structure and decoration, it can be affirmed that Dan Nhiem Communal House is an ancient architectural work bearing the Nguyen dynasty style.

Currently, Dan Nhiem Communal House still preserves many valuable artifacts made of various materials, especially the Than pha and seven royal edicts, the oldest dating from the 6th year of Thieu Tri (1846), which is a valuable source of Han-language documents.

Dan Nhiem Communal House is also the site of the village's traditional festival, from the 11th to the 15th day of the second lunar month. In addition to ritual ceremonies, ví singing, and folk games, there is a palanquin procession for friendly exchange between Dan Nhiem village (quan em) and Hoang Xa village (quan anh). On the fourth day of the village festival, in the communal house courtyard, the giáp in the village still carry sacrificial pigs out to compete. The pigs are pure black, washed clean, and kept in small cages. The pig of the giáp that is largest and best-looking wins a prize. After that, the giáp also slaughter pigs to make offerings for the competition. Therefore, the Dan Nhiem village festival is bustling and lively, attracting many visitors from far and wide to attend and pay homage at the relic.
