First, avoid going out.
As the saying goes, "On the thirteenth day of the first month, the prince urinates badly", which shows how taboo people are on this day, and they don't go out and think that everything is inappropriate.
The ancients thought that the Yan of the underworld was so taboo that mortals should be more careful. Some old people think that this day should be avoided. If they have something urgent to go out, they should also find a sunny time and go out early.
Second, avoid speaking too fast.
On the 13th day of the first month, "Don't talk too fast" means to control your mouth at all times, to prevent disputes with others, to avoid your arrogance, to be forgiven for not talking, and to get into trouble with your mouth, which is not good for yourself and your family.
Third, avoid visiting patients and the elderly.
The older generation thinks that the 13th day of the first month is a "poison day", and it is most taboo to visit the sick and weak elderly, which will affect the patients. It is very unlucky and should not be visited.
