Cửu Long was a province in the Mekong Delta region of southern Vietnam. [1] It was created in 1976 from the merger of Vĩnh Long province and Vĩnh Bình province, and in 1992 Cửu Long was re-split into Vĩnh Long and Trà Vinh provinces. [1]
In Vietnamese, Cửu Long (deriving from the Sino-Vietnamese 九 龍) literally means "nine dragons," referring to the Mekong, known in Vietnamese as the "River of Nine Dragons".
The area of Hong Kong called Kowloon shares a common etymology.
