I have seen the mansion of the Chief Secretary of Guangdong and Guangxi in the late Qing Dynasty. From the gate to the inner hall, there are seven doors, all of the same size and style on a straight axis. Behind this house is a house as a government agency, which has been preserved until 1986 for renovation and sale. This family once supported 16 the famous Mr. Feng Shui in China and presided over the construction of the house. Do those people really don't understand feng shui, seven doors and one line? Modern people are so smart, as long as they see another door from one door, it's like discovering the new American continent, and everyone is shouting, aren't you right? When two doors are facing each other, one will retreat. It has been made clear that it is between neighbors, not a house.
