When the weasel enters the house, it can't be completely said to be good or bad, because as long as you don't provoke it, it will be fine. Not only weasels, but also all small animals. Its attitude towards you depends on how well you get along with it. If you treat it well, it won't hurt you. In geomantic omen, it is good or bad luck for a weasel to enter a house. According to the folk saying, a weasel at home means getting rich, because weasels like to eat mice, and mice are natural enemies of food. If the weasel kills the mouse, the food won't be hurt. Therefore, the weasel is derived from the folk, which means making a fortune.
