Two Vietnamese women on elephant back represent the celebrated Trung Sisters (Hai Ba Trung) in the annual Hai Ba Trung Parade; Saigon; 26 April 1957.

The Trung Sisters (c. 12 - 43 CE); known in Vietnamese as Hai B?Trung (literally 'the two Trung Ladies'); and individually as Trung Tr?c and Trung Nh?; were two first century Vietnamese women leaders who successfully rebelled against Chinese Han-Dynasty rule for three years; and are regarded as national heroines of Vietnam.

The sisters were born in Northern Vietnam; the dates of their birth are unknown; but Trung Tr?c was older than Trung Nh?. The exact date of their death is also unknown but both died in 43 CE.
