Dong Nhan Temple is located in Dong Nhan Precinct, Hai Ba Trung District, Hanoi. The festival of Dong Nhan Temple is held annually from the 3rd to the 6th day of the second month of the lunar calendar.

The temple was established in honour of Hai Ba Trung (Two Trung Sisters) who were proclaimed the heroines of Vietnam as they greatly contributed to the defeat of the Dong Han invaders and the glorious historical pages of the country.

The main festival occurs on the 5th day where there is a ceremony for bathing the statues, opening the back palace, making sacrifices, and light dancing.

A solemn procession of the statues from the temple to the Hong River is followed by many exciting activities at the completion of the bathing ceremony, including the altar-light dance. This dance is performed by 12 young beautiful girls in colorful dresses holding 2 lights in their hands. The festival is finished with an incense burning ceremony.
