You can take a bath on the fifth day of the first month.

You can take a bath and wash your hair on the fifth day of the first month, which is very popular among the people. You can't wash your hair and take a bath from the first day to the third day of the first month, but you can take a bath after the third day, so you can take a bath on the fifth day.

The fifth day of the first month, commonly known as the Broken Fifth Festival, is one of the traditional festivals with a long history in China. It is named after China folklore, and many taboos can be broken before this day. Because this day carries too many people's hopes and longings, there are many taboos in ancient times, such as having to eat jiaozi, not cooking with uncooked rice and not letting women visit. According to the old habit, it is not appropriate to do things on the day of Friday, otherwise something will happen this year. On the "five busy days", it is forbidden to break ground, and there may be disasters.
