A house with good Feng Shui should be surrounded by mountains and water, low in front and high in back, flat in the middle, well-lit, and facing southeast, south or southwest. Mountains in the back give people a sense of security and dependence, while water in the front brings vision, wisdom, and wealth. It is a more ideal situation to have water in front and mountains at the back, because there is an old Chinese saying that you must have a backer. Therefore, there should be mountains behind the main position and the financial position (there should be no water behind the financial position), and some water or waterfalls next to it are fine. As long as it doesn't affect your financial position, you can spread it. So it’s a good idea to put landscape paintings on the back of the sofa!
