Why can't I wash my hair and take a shower on the first day of school?

First, this custom comes from Buddhism, because Buddhism stipulates that Buddhist believers 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. If you wash your hair on the fifteenth day of the first day, it is said to be blasphemous.

Second, there is a water god in the water. The birthday of the water god is on the second day, so you can't wash your hair and clothes these two days, otherwise it will be disrespectful to the water god.

Third, Guangdong customs do not wash your hair on the fifteenth day of the first lunar month, otherwise it will wash away your wealth.

On the sixth day, the official was reported on the seventh day, the life was long on the eighth day, the marriage was held on the ninth day, and the official was added on the tenth day.
