The science of appliance
There is a school of thinking in fung shui that states the electricity that enters your kitchen appliances should be oriented from one of the directions that suits you. For instance, if east is a beneficial direction for you, the cords for your kettle, rice cooker or microwave should enter the appliance from the east. This type of practice has no basis in traditional fung shui and it really doesn't matter from which direction electricity enters an appliance.
Another common fallacy is that the dials on the stove should be positioned specifically according to a person's 'good' direction, based on their year of birth. For instance, believers might insist oven switches lie against a northern wall. This has resulted in unusual and impractical requests for dials and controls to stove manufacturers, but the positioning of electrical or gas stove switches is of no consequence.
Then there is the belief that your stove should back into one of the favourable directions of the head of the household. However, placing the stove at an awkward angle to fulfil this criterion will result in disputes between family members.
