Does the direction of the monument have to be on the bisector of the compass?

The vertical direction of the monument need not be on the bisector of the compass. According to the traditional geomantic theory, there are certain requirements for the vertical direction of the monument, one of which is to aim at the golden line of the compass. The bisector of the compass refers to the line perpendicular to the north-south direction, also known as the due south-north line, which has important azimuth significance. In geomantic omen, the relationship between the orientation of the monument and the environment has an influence on the energy flow and the balance of geomantic energy, not necessarily on the bisector of the compass. This answer is for reference only. Don't be blindly superstitious.
