My family lives behind a dead end. This old house is unoccupied. My family is the second. There is a millstone on the left in front of the gate. Please help me understand Feng Shui.

That friend explained it to you very correctly. People who go out to stay in hotels will not stay in the room at the end of the corridor, let alone stay at home. And the millstone in the left Qinglong is unlucky. There are many millstones in the geomantic omen of Yangzhai ... not to mention the old house. If possible, I suggest you move it somewhere else.
