Mau Temple is a spiritual and cultural tourist destination not only in Hung Yen but also attracts many visitors from all over the country to come and offer incense, worship and pray for peace.
The temple worships Concubine Duong Quy Phi, who was honored as Duong Thien Hau. The temple preserves 15 royal decrees from the Le Dynasty to the Nguyen Dynasty, along with many horizontal lacquered boards, parallel sentences, and large characters praising the loyal and chaste example of Concubine Duong Quy Phi.
This is one of the sacred places of worship in Hung Yen province, attracting the attention of many tourists across the country.

Mau Temple was built in 1278, initially with only one room to worship Lady Duong Quy Phi. Legend has it that the temple was built on the "sleeping dragon" position with a crescent lake on the Red River dike, creating a peaceful and serene "Son Dieu Thuy" position, truly a "Holy land of harmony".
This sacred temple is always filled with incense smoke during Tet and spring, especially in the new year 2025, the number of visitors coming to visit and offer incense is even greater.

In recent years, Hung Yen province has always attached importance to tourism promotion such as strengthening propaganda and introducing the land and people of Pho Hien homeland; diversifying tourism products to create new and unique tourism products imbued with the unique identity of the longan land.
