Please have a look at the master who knows Feng Shui. What's the feng shui like in this building? Can I buy it? The top of the picture is the north. Figure 2 shows the viaduct above the red road.

Every building will be different, not every building.

Even houses in the same building are different.

Different units, different floors and different huxing are very different.

The viaduct should be some distance away, it doesn't matter.
