prepare for Tet holiday, local families do a thorough cleaning of their houses in the days before the New Year comes. The floors will be swept to be clean, windows will be scrubbed, and furniture will be free from dust so that the houses become clean and neat to welcome the most special festival of the year. This traditional activity aims to sweep away anything bad of the past year. In addition, sweeping is a taboo on the New Year’s Day because the locals believe that the good fortune and luck will be swept away.
