In geomantic omen, there are two common modes: Suzaku opening the light and the gate of hell.
The opening of Suzaku is the pattern of the gate facing. If washed away, it will cause quarrels and lead to disaster.
Opening the gate of hell is a problem of Xuanwu's location pattern, which leads to the success of the villain and the disaster of the tongue.
Specifically, you'd better send a picture. I can't see the pattern and I can't tell you clearly.
