Wu Yin, Chengtou map: Wu is not unlucky. What do you mean by not offering sacrifices to ghosts and gods and not tasting them?

Wuyin Chengtou diagram refers to the sixty flowers and five elements of Wuyin branch, which is called Chengtou diagram. E is not affected by the field, and the owner is unlucky. It means that the day of drought is the day when evil spirits are caught in the Arctic. On this day, the landowner's land rights have been corrected, so the landowner has an ominous sign. Yin doesn't sacrifice, ghosts and gods don't taste, which means that when the earth supports Yin, don't slaughter animals as sacrifices to ghosts and gods, and ghosts and gods won't eat these sacrifices in Yin. Why not eat it tomorrow? Because born in the child, the earth cracks in ugliness, life is born in yin, and yin is the beginning of all life, and it is endless. God has the virtue of good life, and ghosts and gods are no exception. You can't kill while you are alive. It is taboo to kill something as a sacrifice to Yin.

The above statement comes from Xu Zhenjun's Jade Sagger: Commemorating the Centenary of Peng Zu's Death.
