Invisible but still exist
The magnetic field on Earth has a profound impact on everything that grows above it, but this effect is surprisingly not easily observed. The human body's blood is rich in iron, the magnetic field of the force has a deep impact on people, but there is no evidence of appearance can be proved; flight thousands of miles, migratory habitats in the seasons of migratory birds, to find out the flight correct orientation depends on the earth's magnetic field, but if you anatomize the body of a migratory bird can not find the organ of the induced magnetic field at all, we only know that these sensory abilities exist, but there is no way to find it clearly it’s place or location.
However, the most precious and admirable feature of Chinese culture is that "although can not see or touch it, I can find and use it for good as long as I am sure of your exist."
It's as though you can not see the air, you can not see the wind, but you can affirm its existence with the touch of your hand. You can also use the fluttering flag, fluttering catkins, swinging leaves, to see the presence.
The magnetic field that affects all things in the world may not be visible or touched. Take at most two magnets to play the game of opposite-sex attraction and same-sex repulsion. However, intelligent wise men of Han culture, from the time of Fu Xi four thousand years ago, have discovered, by observing, recording, thinking and using various media, the patterns of interaction between the magnetic field and all things in the world, one of the wisdom that comes out is the science of Feng Shui that we now know.
From the ancient times, Chinese people in Han culture have initially observed and understood the science of Feng Shui. They saw the rise and fall of different clans in the vast land. Some mighty tribes suddenly perished and some weak tribes were dying, almost to be annexed and destroyed, but after a few years it flourished, not only with the bright and clever future generations, even the livestock breeding are beautiful, full of energy, the other hand, some tribal was more and more weak, even chickens, cats and dogs were sick , lying on the ground lifeless.
At this stage, the connection between people and the science of Feng Shui only ends with the "observation of existence." There is only passive observation about the phenomena of various kinds between heaven and earth, as well as the relationship between phenomena and feng shui.And then integrate useful arguments.
