The five elements give rise to basic feng shui guidelines and play a big part in flying star feng shui as they offer suggestions and solutions on how different sectors of your home can be enhanced or subdued.
A very basic one that you should all know is that it is important to refrain from having too much water in the SOUTH. However, when the flying stars indicate it is auspicious to place water here you can do so (the water will be energizing special water energy here). However, the water feature should never be so big that it overwhelms and conquers the FIRE of the south completely. Otherwise wealth will be attained but at the expense of your good name. Keep all this in mind when deciding on your water feature for the south sector.
