The prayer for cleaning the altar at the end of the year on the 23rd of December in the lunar calendar. Before removing the incense, this prayer must be recited during the end-of-year altar cleaning.

On the 23rd day of the 12th lunar month every year, Vietnamese people have a tradition of cleaning the altar at the end of the year, removing the incense, and rearranging the altar in preparation for the Tet festival offerings. However, before performing these tasks, few consider the need to light incense and ask for permission from the ancestors.
When cleaning the altar, it is recommended to use warm water, wine, or ginger water to clean the ritual objects. Before doing so, you should light incense and offer a prayer to seek permission from your ancestors.
