Is there anything particular about washing your hair on the first day?

Avoid washing your hair and taking a bath on the second day of the lunar new year. Because it is said that the first day to the third day is the birthday of the water god, if you take a bath at this time, it is easy to get the water dirty. In the eyes of the older generation, this is disrespectful to the gods, afraid of bringing bad influence, so it is easy to wash away their good luck. Although there is a habit of taking a bath every day in the south, we still need to pay more attention to it in the second day of junior high school, and the weather is not good in winter. It is easy to catch a cold when washing your hair for a long time.
