Auspicious day of the ecliptic: rushing to the north (Jiazi).

1. Rushing rats (Jia Zi) is an evil in the north-it means that your residence in the north is unfavorable on this day, no matter where it is, it is unfavorable to rats. Jiazi refers to the sky.

2. It's neither important nor good whether the rat is on the scene. Therefore, it is suggested to choose another auspicious day.

The problem of turning on the light should not be so complicated. This is different from the five elements. You should consult a Buddhist.
