Ho Chi Minh City (formerly known as Saigon before the fall of Saigon in 1975) is the largest city in Vietnam and the former capital of the Republic of Vietnam . According to TravelTraffic.com, Ho Chi Minh City is ranked 132 on the list of world's most expensive cities for expatriate employees. Rich in history, tourists often themselves in museums learning about the country's struggles or at the Củ Chi tunnels to experience the war first-handed. As a native, I can also say that street crossing is a nightmare for them (and everyone else for the same matter)!
