The list author says: "I made this list so people who visit me can read and learn about the culture and people in order to prepare for their trip to Vietnam. Sometimes it is hard to sort through the plethora of books focusing on the war to find the books that talk about the whole history of the nation or what the people are like today."
"People who have used this before visiting me seem to be able to comfortably greet others in Vietnamese. They also seem to be familiar enough with the sounds and pronunciation to pick up names more easily. Rosetta stone is also good for training the ear but I think for the traveler this is more effective and useful."
