What does "Little Red Devil" mean?

The fortune teller said that I had committed red evil.

March, June and September are all "Red Evil Days". On this day, praying for blessings, traveling, going to bed, getting married and sharing a room are all red evil days. Big killer. This has nothing to do with Foucault in the eight characters. Foucault belongs to the category of geomantic omen, and Foucault belongs to the category of divination of the five elements and ten gods. The two have nothing to do.
