Changing geomantic omen is an environmental science. Environment affects people, environment changes people and environment makes people. Simple way, if the place where you used to live is relatively smooth, you will definitely move back to a different place from where you live now. Feng shui is different, and there will be some changes. In a few cases, feng shui has not changed much. Be cautious if you don't know each other's details. Few people really understand these things, but most people are fooling people!
