The toilet is where Yin Qi exists in the mansion. If the office wall is close to the toilet wall, you can't set a desk next to the toilet wall, because the edge of this wall is easily hit by the toilet, urinal or toilet faucet, which are extremely fierce evil spirits and have great adverse effects on your health.
If there is no way, you must sit next to the toilet wall, and you can only solve some of its suffocation, but not completely.
The solution is to sit as far away from the wall as possible, hang a small compass on the wall between the seat and the wall, and put a basin of mud on the ground.
