Feng shui is definitely getting more and more clear. Many people say that the compass is useless when it is not used in early geomantic omen. Understand that the early geomantic compass is not perfect, and it is difficult to get it easily from the market. They are all handmade, and a compass will be handed down for generations. So at that time, the absence of a compass was also an important factor, not the absence of a compass. Feng shui itself is a combination of magnetism, orientation, yin and yang. If there is no compass, you can't find the direction, you can't tell the difference between good and bad, and you can't evaluate the quality of Feng Shui. Of course, you really don't need a compass to see the feng shui environment. When you are accurate to the specific position and orientation, you must have a compass to participate.
