It is hard to say which name is more popular now: Saigon or Ho Chi Minh City. To most young people, Ho Chi Minh City is more common while to most older generations (the middle-aged and elderly people), Saigon is still deeply in their mind.
The name Saigon, adopted over 300 years ago, was originally used to indicate an area of 1 km square where there were a lot of Hoa people (Chinese) living in the 18th century which is now known as the Chinatown or Cholon. It is said in the past, there were lots of woods and cotton trees in this area which yielded its name Saigon. Based on Chinese and ancient Vietnamese phonetics, “Sai” means “woods” and “gon” means “Cotton tree”.
However, this evidence is not strong enough to be an official explanation for the name Saigon. Besides, some people believe Saigon was derived from “Prei Nokor” , a former Khmer palace of Angkor Dynasty where there was a large community of Khmer people living before the expanding the country process of Nguyen Dynasty. That is the reason why most older people are more comfortable with the name “Saigon”. It is not only a historical name but also a part of their daily conversation since the very first days moving to the South.
The name, Ho Chi Minh City, officially became the name for Saigon in July, 1976 to honor the first prime minister of Vietnam, also the national hero Ho Chi Minh, a famous figure in Vietnam’s struggling and liberating history. Because it has just been used for over 30 years, Ho Chi Minh City is more popular to young people.
However, due to some phonetic characteristic, the name Saigon is used mostly by foreigners who come to visit Vietnam. Saigon is shorter and easier to pronounce,though!
