Vietnam is the jewel of Southeast Asia, a country thousands of years old. Its official name is "The Socialist Republic of Vietnam". Vietnam has been invaded and colonized many times throughout history. United States will receive little animosity in Vietnam despite the Vietnam War. The only political party in Vietnam is the Communist Party. Vietnam has a 5% return rate on tourists visiting the country. There is a sizable China population living in Vietnam. Buddhism is the major religion. Tet is Vietnam's biggest holiday, kind of like if you rolled Thanksgiving, Christmas, and New Year's all into one. Tet occurs between late January and March. Fortunately, almost all of Vietnam's major tourist attractions can be visited by traveling south from the capital, Hanoi, to the largest city, Ho Chi Minh City, (commonly called by its old name, Saigon).
