The unit of measurement is symbolized by the letter 'L,' with each L divided into 8 large arcs representing different corresponding meanings.
The significance of the ruler is crucial and holds high importance in feng shui. Specifically, if you construct a house in the right direction on an auspicious day, those choices are only relatively estimative.

3. Important Considerations in Designing Staircases
When determining the number of steps in a staircase, consider the limits of the two floor slabs, counting from bottom to top.
Some areas, known as landing spaces, are treated like regular floors and are not included in the step count. For instance, a landing that serves as the upper floor's surface.
There are also significant landing spaces, such as transition areas or stair landings, that do not function as regular floors but are still considered in the step count.
It's advisable to calculate the number of staircase steps with clear dimensions beforehand, ensuring that the last step between two floor slabs falls into favorable arcs: Talent - Virtue - Authority - Essence.
