Tet celebrates Chinese New Year (late Jan), and is a time for Vietnamese families to get together and feast. The streets glow pink with flowering peach trees – a symbol of new life and good fortune – and stalls sell sweets, kumquat bushes, fruit, and flowers, turning the city into a riot of color. There are fireworks and parades, and firecrackers are thrown to ward off evil forces.
Tết, short for Tết Nguyên Đán, Spring Festival, Lunar New Year, or Vietnamese Lunar New Year is one of the most important celebrations in Vietnamese culture. The colloquial term “Tết” is a shortened form of Tết Nguyên Đán, with Old Vietnamese origins meaning “Festival of the First Morning of the First Day”. Wikipedia
