Secondly, in terms of geomantic omen, if the sewer pipe in the bathroom goes from the top of the bedroom, it may affect the indoor geomantic omen, because the bathroom is a place where people shelter evil people and shelter evil practices, and if the water pipe goes from the top of the bedroom, it may affect the indoor air quality and hygiene.
Finally, if the sewer pipe in the bathroom walks on the top of the bedroom, it may affect the indoor safety, because if the water pipe fails, it may affect the indoor water safety.
Therefore, from the perspective of geomantic omen and safety, it may not be appropriate to walk on the top of the bedroom with the toilet sewer pipe.
