When can I wash my hair during the Spring Festival?

People think that the days that are not suitable for shampooing are mainly the first day, the second day, the third day, the seventh day, the thirteenth day and the twenty-ninth day of the first month.

The custom of not washing your hair on the fifteenth day of the first day comes from Buddhism, because Buddhism stipulates that Buddhists should fast, recite scriptures and worship Buddha on the fifteenth day of the first day of the first day, 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. There is a water god in the water, and the birthday of the water god is on the second day of the first grade, so you can't wash your hair and clothes these two days, otherwise it is disrespectful to the water god.
