In a normal house, the kitchen is located at the back of the house, but some houses are located at the entrance because of limited space. If the residents are unmarried and single aristocrats, that's all right, but it's not good to assume that they are married, because they usually ignore the image when cooking food. If there are guests at home, who wants to be seen like this, or when you open the door, outsiders can see their cooking virtues in too many chefs at a glance. Another feng shui factor is that the stove is a place to make money. Outsiders who come into the door to see the kitchen will cause money loss or loss, and the investment may be wiped out.
