In the art of Feng Shui there is no symbol of money more powerful than water.
But not just any water. If you want to have all the beneficial chi energy that will bring you health and prosperity, you must incorporate water the right way and keep it clean and fresh at all times.
Consider incorporating water symbols and water features into your workspace. A good choice for this is an aquarium, preferably with goldfish in it, since gold is a symbol of money in Chinese culture.
You can also build in tabletop fountains, just make sure the water flow isn’t very fast or blocked. A great idea for the office is a scaled down desk fountain designed for a smaller space.
