Standing at the entrance of Qin Gang's factory, Tang Hao looked at the factory opposite them.
The factory opposite them was much bigger than Qin Gang's factory and had several tall buildings in its compound. Two of the buildings were built in a peculiar manner. They formed an acute angle when viewed from where he stood.
The angle was pointed straight at the entrance of Qin Gang's factory.
In the study of fengshui, that formation was known as the Pointed Hex.
The Pointed Hex could easily change the fengshui of an area. Negative qi would be concentrated at the point where the angle was aiming at.
If someone lived or worked at the point of concentration, negative qi will enter their bodies, and their bodies would soon become sluggish and easily tired. In more serious cases, they might fall into a coma.
Usually, building walls form right angles rather than acute angles.
