How about the fifth day of the first month?
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.
Don't comb your hair on the fifth day of the first month. Hair symbolizes good luck for a year. It starts from scratch and disappears as soon as you comb your hair. The older generation thought it was unlucky to comb it off on the fifth day of the first month. On the fifth day of the first month, it is forbidden to break ground, otherwise there may be disaster.
In folk customs, "Breaking Five" has a sense of ceremony. According to legend, the God of Wealth's birthday is on the fifth day of the first month, which becomes an auspicious day for people to welcome the God of Wealth, especially for businessmen.
