What did the ancients say about human evil?

Geomantic omen theory: it is to suddenly encounter something that collides with people. It can be understood as cold, wet cold, abnormal brain waves and so on. ...

Scientifically speaking: suddenly encountering too hot or too cold air (a wisp) will make people's reflex nerves react. Excessive stimulation will cause endocrine disorders in the body, which will lead to physical reactions such as physical discomfort, poor blood supply to the heart and wrinkled skin. . . It can even lead to extreme changes in mood. . . .

The ancients were very clever. Something that cannot be scientifically understood. It can be summarized as middle evil: in fact, a wisp of cold air or brain waves (sounds) floating and spreading in the air can be classified as middle evil. . . . Because it is an invasion from outside the human body.
