Which direction of underground sewage pipe is good for feng shui?

Fang Kun and Genfang of the house are well drained. Fang Kun and Roots of a house belong to soil in the five elements, and soil can hold water. So why can water be discharged in this direction? This is because soil and water become wet soil, and wet soil can produce everything. Here is an image, not just the generation of five elements. However, it can also be considered that the earth made water to prevent the water from overflowing too much, and then there was a good result. This answer is for reference only, please don't be blindly superstitious.
