2. The entrance floor is not buried here. If buried under the floor of the kitchen door, the effect will be different, because the door is the main air inlet and the kitchen is a small indoor air inlet. Unless the kitchen door is opposite to the bedroom or bathroom door, it can be buried under the lintel floor of the kitchen door.
3. Please refund the five emperors' money depending on the type. If it is five copper coins or a simple string found in the market, it needs to be dried in the sun before it can be used. If it's a strong feng shui style with accessories, and it's treated by feng shui, such as five emperors' money for a long time, you don't have to deal with it, just follow the order of Zuo Shunzhi and Jiaqing.
