What are Yin Feng Shui and Yang Feng Shui?
Classical Feng Shui has two different branches: one is dealing with the graves and burial sites (spooky!) and the other one is ealing with the houses of the living. They are called Yin and Yang Feng Shui.
As a Feng Shui consultant when I do a Feng Shui consultation for a home or business in London or somewhere else I use the Yang form of Feng Shui.
Here are more details about these two important branches of classical Feng Shui.
1. Yin Feng Shui
Yin Feng Shui is the form that deals with the burial sites and remains of the livings. In Hong Kong or Malaysia for example it is not rare to call a Feng shui master in when someone has passed away. His role is to decide the emplacement of the ashes urn in a columbarium, or an auspicious location for the burial site and when should the tombstone be raised. The site where a body lies will impact the life of his biological descendants through the Chi it receives, hence the importance of Yin Feng Shui. Yin house fengshui, yin dwelling are names also used.
2. Yang Feng Shui
Yang Feng Shui is the part that deals with the houses and workplaces of the living. This is the most widespread usage of Feng Shui. The rules used in Yang Feng Shui must be traced back to their root in Yin Feng Shui. Internal and external Water exits principle for example comes from principles applied around a burial site in Yin Feng Shui. A principle that is not related to a former rule in Yin Feng Shui has to be regarded as dubious, like many modern-day additions that have nothing to do with authentic Feng Shui.
