Does the left, bottom and right height of architectural geomantic omen refer to the foundation of the building or the height of the building?

The house-sitting feng shui is very particular. As the saying goes: left green dragon, right white tiger, former Suzaku, after Xuanwu, that is to say, there should be dragons and tigers on the left and right sides of the house, and the position of green dragon is higher than that of white tiger; There should be mountains like turtles and snakes behind, and the phoenix can spread its wings in front of the house, which is very good feng shui in line with this terrain. It can be seen that Xuanwu is a winding mountain range and Suzaku is an open hall.
