According to the general principle of geomantic omen, the toilet should be placed at due north 15 degrees. Northeast (ugly range) 15 degrees. The direction of the toilet should be opposite to that of the house. For example, the house sits east facing west, that is, the gate faces west. Then, when people sit in the toilet, they should face east. If the direction of the house faces north, that is, the direction of the gate faces north, then people should face south when sitting in the toilet; If the direction of the house faces east, that is, the direction of the gate faces east, then people should face west when they take the toilet. If the toilet and the house are in the same direction, there will be taboos, which will easily lead to chronic family members.
The ancients believed that the toilet could not be adjacent to the altar, otherwise, it would be a disgrace. Altar, considered by the ancients as a place to worship ancestral tablets or religious idols, is also understood as a pendulum by modern people.
