What do you mean by eight kills in geomantic omen?

Pronunciation bā shā

Interpretation is also called "eight evils". In ancient times, astrologers used nine planets to calculate their fate. Their eighth house was called the Sick Urbana Palace, also known as the Eight Killings Palace, or "Eight Killings" for short.

The source of Tang Du Mu's "Self-Written Epitaph" is: "Born in the Horn Star, finished in the Horn Star is the eighth house, called the Sick Palace, also known as the Eight Killing Palace, where Saturn is located." Song Zhou Mi's "Dong Qi's Wild Words Descending Immortals": "Distinguish (distinguish) goodness from five stars, and every time you say eight evil spirits, the hours are eight evil spirits."

For example, Tian Kun Hong Rengan's "Senior Minister's New Chapter": "Change the paradox of Yin and Yang."
