Why can't I take a shower on the fifteenth day of the first day?

1, this custom comes from Buddhism, because Buddhism stipulates that Buddhists should fast, recite scriptures and worship Buddha on the fifteenth day of the first lunar month, which is actually equivalent to Sunday in the west. People must pack up before the first and fifteenth day of junior high school. On the first day and fifteenth day, I will go to the temple to burn incense and worship Buddha and pray for peace.

2, water has a water god, the birthday of the water god is on the second day, so you can't wash your hair and wash clothes these two days, otherwise it is a big disrespect for the water god.

3, Guangdong custom, you can't wash your hair on the fifteenth day of the first day, otherwise you will wash away your wealth.
