Having lost, Sầm Nghi Đống (Chinese: 岑宜棟) fled and refused to fall into the hands of the Tây-Sơn by hanging himself on Ốc (Loa Sơn) hill.

After the war, in order to promote diplomatic relations with the Qing, Sầm Nghi Đống was returned for a state burial and resident Han Chinese were allowed to build a temple on today's Đào Duy Từ street.

After the battle, King Quang Trung ordered the bodies of the enemies to be collected and put into 12 large burial mounds.

[1] In 1851, during construction and clearance work for new roads and the Nam Đồng markets, more remains were found and gathered into a big burial next to Ốc hill.

From then on, the Đồng Quang Pagoda organized an annual religious ceremony to commemorate the Đống Đa Battle on the 5th day of the Lunar New Year.
