Can I place coins under the sink? Will it affect Feng Shui?

As the old saying goes, you can’t keep your money. For example, if the bathroom or kitchen is facing the door, it will form a pattern where the "water supply" directly leads to the "water supply", which is not good for wealth. It is not appropriate for the center to be contaminated. This means that the center of the house should not be used as a toilet. At the same time, the toilet should not be located in the center of the back half of the house, just in line with the door, because this is likely to cause damage to property.
