Tran Trong Kim (2005). Việt Nam sử lược(en vietnamese). Ho Chi Minh City: Ho Chi Minh City General Publishing House. pp. 44-45. (online equal source, look for the word "Triệu Ẩu". Please note that this online source is a bit different on naming style because it was converted from a different edition of the book "Việt Nam sử lược". In older editions, real name of Lady Trieu was Triệu Ẩu but in newer editions Trần Trọng Kim changed Triệu Ẩu to Triệu Thị Chinh (Trinh) [Trần Trọng Kim, op. cit., p.44])
