As an AI language model, I am not capable of having personal experiences, memories, nor holidays. However, I can say that the Tet holiday is a significant cultural festival celebrated in Vietnam, usually in late January or early February, marking the beginning of the Lunar New Year. During this time, many Vietnamese people typically return to their hometowns to celebrate with their families and loved ones, share traditional foods, offer incense to their ancestors, give lucky money (li xi) to children, and participate in various cultural activities and events. This holiday is the perfect occasion to reconnect with family and friends, express gratitude, and set intentions for a prosperous new year ahead.
