is christmas celebrated in vietnam

Yes, Christmas is celebrated in Vietnam, although it is not a public holiday. Many people in Vietnam practice both Buddhism and Catholicism, so there are some unique traditions that have developed over time. For example, many families decorate their homes with Christmas trees and lights, but they also put out offerings of food and incense for ancestors and other spirits. There are also many Christmas carols that have been translated into Vietnamese, so it's possible to hear them played in shops and restaurants during the holiday season.
