Do you still need to choose an auspicious day to be a screen wall outside the gate?

It all depends on the date, that is, choose some auspicious days. According to the relevant network data, it is found that the shadow back wall should not be too high, in order to block the geomantic omen between the inside and outside, and it will not be the geomantic omen isolation caused by the fierce geomantic omen struggle between the inside and outside. When building, it must not be too big, and it is generally not more than the relative height of the gate.
