How to treat the eight evil spirits on the compass and what role do they play?

what do you think? Look at it this way: "Kanlongkun rabbit shakes the mountain monkey, the chicken dries up the head of Ma Dui snake, and the tiger leaves the pig as a demon, so close the tomb at any time." What role does it play? Mainly to avoid the mistakes in the orientation of the house tomb, to prevent the eight evil spirits from returning to the palace, and to avoid the disaster caused by the burial mistakes within 100 days. Secondly, it can also be used to choose the day. These eight evils, such as Jiazishui and Ugly Earth, are all evolved from the officials and ghosts who run around every day. It doesn't depend on heaven, and it belongs to the five elements with good and evil, but its usage is based on the gossip that heaven and earth are integrated into one. The five elements start from six, and sons, fathers, financial officials and brothers, officials and ghosts are fierce. Nowadays, geography students generally don't understand the examples and functions of the eight evils. Anyway, it doesn't matter what others do! But he became a master as soon as he got fat, hehe!
