Tết is the biggest celebration in Vietnam, bringing a lively and warm atmosphere. Before Tết, people prepare by shopping, cleaning their homes, and decorating with peach or apricot blossoms. On Tết, families gather for a reunion meal, exchange best wishes, and give lucky money to children. Activities like lion dances, fireworks, and visiting friends and family are popular. After Tết, people slowly return to work and school, but they carry the spirit of the new year with them, filled with hope and positivity for the coming months.
