The French writer Marguerite Duras lived in Sa Đéc during the three- to four-year period between 1928 and 1932. Her mother ran a school on the corner of Hùng Vương and Hồ Xuân Hương, where a school still exists today (now it is Trưng Vương Primary School). Duras met Huỳnh Thủy Lê, the son of a wealthy Chinese family, and the two became involved in a love affair that became the basis for Duras's 1984 Prix Goncourt-winning novel, The Lover. The house of Huỳnh Thủy Lê, at 255A Nguyễn Huệ Street, for many years an office for a government agency, has from 2007 been open to the public, with guides offering tours in French, English and Vietnamese.
