It turns out that the whole villa next to the kitchen has a septic tank. Now I want to expand the kitchen and move the septic tank to expand the kitchen. Is it feasible in geomantic omen?

It is best not to do this, because the kitchen is in charge of people's intestines and stomach, and the septic tank belongs to Huang Wu evil spirit in geomantic omen. If we have to expand the kitchen here, it will affect the health of our family. If you have to do this, there is a trick in Feng Shui called looking at the sky. After the septic tank is dismantled, dig three feet deep, set off firecrackers in the middle, then take fresh soil from the countryside to fill three feet, and then cover the middle with a piece of red paper. After three days and three nights, it will be fine.
