The Ox Days in March, June and September are all "Red Evil Days". Praying for blessings, traveling far away, setting up a bed, getting married, and having sex on this day are all violations of the Red Evil Day. Big bad. This has nothing to do with Kefu Kezi in the horoscope, and committing red evil belongs to the category of Feng Shui, while Kefu Kezi belongs to the fortune-telling category of the Five Elements and Ten Gods, so there is no big connection.
