"Li xi" is an important part in Vietnam's customs of Tet Festival, especially with children. It is
a small amount of money that can bring good fortune to the upcoming year. However, "li xi" is
not limited only on the first day, but can even last to the 9th or 10th day of Tet Festival, and
given when the adults first met the kids.
Besides the money, the tiny red envelope also has its own meaning. It represents the secrecy
and privacy to avoid comparison as adults want children to regard the money as the gift of New
Year, instead of being jealous of receiving less than other kids. The red color, the most popular
color appearing in Vietnamese festivals, signifies the prosperity and great luck according to
Asian's beliefs.
In the morning of the first day of Lunar New Year, children and parents will visit grandparents'
home, wishing for a happy new year and great health, showing respect and gratitude, and giving
gifts. After that, it is grandparents and adults' turn to give children lucky money to welcome
their new age.
