From my understanding, a key to Feng Shui is the balance of Chi the universal energy. The purpose of the arrangement of objects such as furniture and adding enhancing objects within the map of energy areas is to create balance. That will cause a natural flow.
Understanding Feng Shui takes a little bit of reading. If not done then it may only be decorating by gut feeling. But, gut feelings may be influenced by a natural connection to Chi. So, to say it is right or wrong is an open book subject to interpretation.
