How important is soil to the choice of cemetery feng shui?

Both above-ground Feng Shui and underground Feng Shui must be taken into consideration. The above-ground Feng Shui is based on the sand-water theory, and underground Feng Shui is better if you see yellow soil; avoid bad water (the valley is called a soft cone), because If it is placed on the back of the deceased, it will be unfavorable to the descendants; avoid seeing hard stones (called hard cones) to show that the descendants are poor and hard, and this is also called the yak land; avoid seeing ants (commonly known as live cones), because the ants will eat them The flesh and bones of the deceased are harmful to future generations; avoid seeing a coffin with a coffin (called a cone of death) on top of the coffin, as this will be more harmful to the deceased or harmful to the earth master; avoid having a cold wind tunnel, test whether there is a wind tunnel. Method: Use a candle Light it against the entrance of the cave. If the lamp head does not move, it can be used. If the lamp goes out and it becomes a wind tunnel, it will cause disaster (people who respond to disasters will be judged according to the good or bad luck of sand and water). If the well is usable like this, then smell it. If the smell is like milk, it means your land is noble. It will be a good fortune, official seal and son's interest. If there is a strange smell, it will be auspicious and reduce the power;
