Since the Vietnamese believe that the first visitor a family receives in the year determines their fortune for the entire year, people never enter any house on the first day without being invited first. The act of being the first person to enter a house on Tết is called xông đất, xông nhà or đạp đất, which is one of the most important rituals during Tết. According to Vietnamese tradition, if good things come to the family on the first day of the lunar New Year, the entire following year will also be full of blessings.
