According to the traditional view, this day is not suitable for bathing, because washing your hair may wash away your wealth, and bathing will also make your money lose. And there is a saying that the birthday of the water god is on the second day of the first month, so you can't take a shower and wash clothes these two days, otherwise it is disrespectful to the water god. However, with the evolution of the times, some people are not strict about customs, but we still need to pay attention. As the first day of the Spring Festival, we are all looking forward to a good start. If we wash our hair, we have no beginning, which is not a good morality.
Don't break bowls, mirrors and other glass and ceramics on the first day of the lunar new year, so as not to break the money. If it is accidentally broken, the remedy is to wrap it in red paper, put it on the altar first, and say "Peace through the years" and then throw it away after five days. Avoid bathing, washing your hair and washing clothes on the morning of New Year's Day, so as not to wash away your fortune. Don't call others' names to wake people up on New Year's Day, which will make them be urged to do things all year round. In ancient times, the poor couldn't afford porridge on the morning of New Year's Day, so they avoided eating meat and taking medicine. Eating porridge on the first day of the new year will lead to poverty for a whole year. In addition, it is not suitable for eating meat on New Year's Day. Therefore, there is a saying in southern Fujian that "eating vegetables early in the first day is better than fasting for one year", and try not to take medicine on the first day. Unless you are seriously ill, healthy people are not suitable for this kind of life. We should not cook new rice on the first day of the new year, but eat the leftover New Year's Eve dinner. I can't eat last year's food, and there will be some left this year. Don't take a nap on New Year's Day. According to the old adage "No sleep during the day", people are advised not to be lazy. Taking a nap on New Year's Day will affect their career. Do not wash clothes on the first and second day of the New Year's Day. It is said that these two days are the birthday of the water god, so don't wash clothes: you can't use a broom on the first day of the first month, otherwise it will sweep your luck and ruin your fortune. If you must sweep the floor, you must sweep it from the outside to the inside. Today, many places still keep the custom of cleaning before New Year's Eve. On New Year's Day, don't put brooms, don't take out garbage, prepare a big bucket of waste water, and don't spill it outside that day. You can't smash furniture during the New Year. Breaking it is a sign of bankruptcy. You have to say "Peace through the years" or "Flowers bloom on the ground, wealth and splendor" as soon as possible.
Solemnly declare: the answer is for reference only, please don't be blindly superstitious.
