Building another floor on top of the original house will increase the area of the house, which is what we like to do in the countryside now. Why can't we build another floor in the ancient proverb? It is because houses in rural areas used to be adobe houses, but most of our rural houses are brick houses now, and the firmness of foundations and floor tiles is much stronger than that of adobe houses in rural areas. Of course, this sentence does not mean that the present countryside is not practical, because the foundation will be laid before building a house, and the foundation determines the height and weight of the house it bears. If the foundation can only bear the original floor of the house from the beginning, then if you want to build another floor, you must rebuild the foundation, otherwise the house will become a dangerous building.
Opening a pond at the door involves the geomantic problem of building a house. Although people in rural areas always think that mountains and water are a good sign, opening a pond casually will touch certain geomantic problems and involve life risks, especially those with old people and children at home, who are likely to fall into the pond and drown at night, especially some children who are only two or three years old. Their self-care ability is very poor, and their families must follow them anytime and anywhere.
So, there is the last sentence, why do you say that the family is ruined? In fact, this proverb now expresses some of our basic safety awareness.
