Hoa Dong Communal House

According to village elders: In the first decades of the Common Era, northern invaders swept down to invade our country; the Trung Sisters raised the banner of uprising. In the war to save the country against the enemy, in this land bearing historical traces, the two generals Cao Son and Do Ly fought tenaciously against the invading Han troops. Today traces of citadels, ramparts, moats, and stakes can still be recognized. This was the site of the insurgents' arsenal of arrows, spears, and javelins. Hence the name Dong Lao.

In the time of Dinh Bo Linh, he raised troops to quell the rebellion of the 12 warlords. As a child, he used reed blossoms as flags for mock battles. He stationed troops and trained in the guava garden. When he won and ascended the throne as King Dinh Tien Hoang, he returned here to perform sacrifices. To commemorate the historical site of the insurgents with reed flags, it was called Dong Lao Village. Later it was changed to Hoa Dong Hamlet, Bach Sam Canton, Son Minh District, Ung Hoa Prefecture. Today it belongs to Dong Thinh Hamlet, Ung Thien Commune, Hanoi City.

Hoa Dong Communal House still preserves the original deity genealogy book 'Hung Due Vuong Trieu Cong Than Nhat Vi Dai Vuong Pho Luc Can Van Bo Thuong Dang Quoc Trieu Phong Chinh Ban' compiled in the 6th year of Vinh Huu (1740).

The Great Hall and the Rear Hall are arranged in the shape of the character 'dinh'. The outer Great Hall has five bays; the central bay, in the 'dinh' character layout, has a three-bay Rear Hall extending backward in a pestle-handle style.

Hoa Dong Communal House currently preserves 1 deity genealogy book recording the deeds of the deity Cao Son Dai Vuong; he was a general under King Hung, credited with fighting the enemy and defending the country of Van Lang, and was worshipped by the people of Hoa Dong as the village guardian deity; 15 royal edicts from the dynasties of the Vietnamese feudal state, from the Le to the Nguyen era, conferring honorific titles on him; 1 throne and deity tablet inscribed with his divine title and honorific names; ritual objects of value in religious art such as horizontal plaques, couplets, a palanquin carved with dragons and phoenixes, and 2 stone steles recording the deeds of the deity Cao Son and the history of the communal house's construction. These steles were made in the Nguyen era.
