Lu Xun said: "Foreign countries use compasses to sail, but China uses them to see Feng Shui." What is the essence of this?

First of all, China has lived on land since ancient times. In ancient times, people's things mainly came from land, so sailing was very backward. And some western maritime powers are mostly poor in products. Most of them come from the ocean, and in order to survive, they seek out. Due to the undeveloped science and technology in ancient times, geomantic omen is very common in China, and there are orientation restrictions in geomantic omen. So the compass has a very different purpose in putting things.
