Behind the cashier is a tempered glass wall. What's the saying from the perspective of geomantic omen?

In the geomantic omen of Yangzhai, tempered glass, glass and mirror belong to yin, which brings its own suffocation, which is not conducive to wealth accumulation. If you put it in a fierce position, the result will be even worse, not only will it not accumulate wealth, but it will also be unhealthy and have a greater impact on women. The way of doing business is very important, and the location of the cashier is even more important. Because every household's house [including merchants' shops], as long as the entrance door does not change its position at will, the orientation of gathering wealth is fixed.
