The Phuong Ngoai Communal House relic was built long ago to worship the three deities who protect the spiritual life of the people according to traditional beliefs. The origins and deeds of the deities are recorded and passed down among the people as "superiors" who always listen to and understand the people's sorrows in order to protect and shelter them.
Historians affirm that during the period of Chinese domination and resistance against it, lasting more than 1,000 years, Ly Bi's uprising in particular and the Early Ly dynasty in general held a very important position, because Ly Bi's uprising achieved the most resounding victory and won the longest-lasting independence and autonomy. In the nation's history, Ly Nam De was the first person to proclaim himself Emperor and also the first to establish the era name "Thien Duc". Ly Nam De was also the first to recognize the central position of the land of ancient Hanoi... Relics worshipping Ly Nam De are now scattered across the provinces of Thai Binh, Thai Nguyen, Hanoi, Vinh Phuc, Phu Tho, etc., including Phuong Ngoai Communal House in Lien Minh commune.
Besides the two deities mentioned above, the communal house also worships Thien Cuong Dai Vuong, who rendered meritorious service to the country during the Hung Kings period. At the same time, in Phuong Ngoai locality, he directly taught the people how to make a living and improve their lives to achieve what they have today; truly great merit.
