Does building a garage ditch under the foundation have an impact on Feng Shui?

It doesn't matter if you pass under it. After all, you can still build bricks or pour them on it.

It is suggested to leave some live bricks on the cover, which can be dredged in case of blockage.

How many houses in the city are under the drainage ditch, drainage on the same floor or something, nothing; Even if the car is parked, it can bear enough weight and has no influence.
