Refrain from positioning your bed directly under a beam. A beam may create feelings of pressure that can disrupt your sleep. If you have no other options, cover the beam with fabric or hang 2 bamboo flutes from the beam with the mouthpieces pointed downward. This will help block some of the unwanted energy coming from above the bed. The idea is that you don't want to feel threatened in your sleep.
Live plants have their own chi and will draw chi to them. Don't have a green thumb? "The next best thing is to showcase high-quality silk plants and flowers — not plastic," says Varone. The best places for plants are in the kitchen (between hot and cold appliances to create balance), in the dining room (to draw abundance), and in the family room (to promote health, life, and connection).
Directly connected to the concept of a clutter clear space is clear organization. If you do not have an organized house, chances are you will start quickly accumulating clutter again. Each item in your home deserves a space of its own, no matter how small; this makes for a peaceful house with strong and clear energy. Think about it and look for the best organizational systems you can find; there is an abundance of them out there, from Ikea to California Closets and everything in between (Home Depot, Bed, Bath and Beyond, The Container Store, etc).
The main tools used in feng sui are the compass and the bagua. The bagua, or the energy map, is an octagonal grid containing the symbols of the I Ching, the ancient oracle on which feng shui is based. The Compass , or Luo-Pan, is used to access the deeper information of a building. It consists of bands of concentric rings arranged around the magnetic needle.
The five elements can interact in any number of ways, some constructive and some destructive. In the constructive cycle, for example, water provides moisture for trees (wood) to grow; wood then becomes a fuel for fire; the residue of fire is ash or soil; the ash/soil is the essence of earth minerals that form metals; and as metal cool, they allow water to condense, completing the cycle. In a destructive cycle, on the other hand, metal can cut wood; and wood can grow over and consume soil.  
Nonetheless, after Richard Nixon journeyed to the People's Republic of China in 1972, feng shui became marketable in the United States and has since been reinvented by New Age entrepreneurs for Western consumption. Critics of contemporary feng shui are concerned that with the passage of time much of the theory behind it has been lost in translation, not paid proper consideration, frowned upon, or even scorned. Robert T. Carroll sums up what feng shui has become in some instances:
In Feng Shui, we use the “commanding position” to locate important furniture such as your bed. The bed is arguably the most important piece of furniture to put in the commanding position because you spend so many passive hours sleeping! To place your bed in the commanding position, you want to be facing the door while not in line with the door while lying in bed. Ideally you can be diagonally across the room from your bedroom door. However, I understand this is not always possible. In that case, find a mirror and place it so that you can see the door while lying in bed. I suggest freestanding mirrors, as they’re easier to move around and get just right.
The third option of a good feng shui bedroom layout has the bed on the same wall as the door (or the nearby wall), but with the bed being well protected and grounded.  If this is the layout that is most suitable for your space, be sure you leave as much space as possible between the door and the bed, while still allowing enough room for the second nightstand (the one on the side further from the door.)
The new house you just bought can be a feng shui disaster. You can save yourself a lot of grief, loss and misfortune in years to come. You will be living in the house quite a long time, hopefully for a lifetime. So you must look for a good feng shui house that helps you pile up wealth and nurture great relationships and brings you health, happiness and vitality. 
As of 2013 the Yangshao and Hongshan cultures provide the earliest known evidence for the use of feng shui. Until the invention of the magnetic compass, feng shui apparently relied on astronomy to find correlations between humans and the universe.[3] In 4000 BC, the doors of Banpo dwellings aligned with the asterism Yingshi just after the winter solstice—this sited the homes for solar gain.[4] During the Zhou era, Yingshi was known as Ding and used to indicate the appropriate time to build a capital city, according to the Shijing. The late Yangshao site at Dadiwan (c. 3500–3000 BC) includes a palace-like building (F901) at the center. The building faces south and borders a large plaza. It stands on a north–south axis with another building that apparently housed communal activities. Regional communities may have used the complex.[5]
