Many traditional rules for mothers-in-law: no bathing, no washing hair, no taking out the trash, no sweeping the floor on the first day of the lunar new year.

A southern daughter-in-law visiting her husband's family in Hebei for the first time, wanted to take a shower in the morning but was yelled at, "All your wealth is washing away!" She was stopped from washing her hair and had to hold it in until the second day of the lunar new year to secretly wash, feeling like a greasy rice cake that hasn't been washed during the New Year.
Is it the same where you are?
