Personally, I think that determining the year of construction is too pedantic to explain the rise and fall of different people in the same house. Feng shui is still dominated by people. Empty houses have no soul and lack soul.
Therefore, the delivery should be based on the occupation time of the stove. It has nothing to do with decoration or not. For example, my house has been completely renovated, but the stove has not been changed, and I will continue to transport the previous house; Similarly, I didn't decorate it, just changed the stove, and when I changed the stove, the house transportation became a house transportation. Therefore, during the transformation of the "Three Yuan Nine Games", whether the cooking stoves are replaced or not can continue or change the housing transportation.
This method is taken from Su Minfeng's geomantic theory, which is practical, so it is adopted.
