Do you know that a Chinese Loupan (Chinese Compass) can be used as a ghost detector?
I have on a few occassions did Feng Shui audits and have to throw away the Chinese Loupan!
What happened was that during my Feng Shui audits, if the Chinese Luopan's center needle moves round and round it means that it has detected a ghost! Usually, I notice that it occurs in the North-East part of the house or building! On occassions after this, I would fall sick and had to quickly throw away the Luopan.
Take it this is part of the health hazard of a Feng Shui practioner! I think if my insurance company knows this, I would be have to pay a high premium or totally banned from taking up insurance. In the league of stuntman etc.
In case you do run out to buy a Chinese Loupan for your home, please do not use it as a display item as the trigram on the Luopan can be " overpowering ". It should not be displayed like any other object but kept properly in a `respectable' place.
Wait! If you do not understand Mandarin, it is ok! If you intent to buy a new house, you can bring it along to check out the house just by looking at the centre compass on it for any unusal activities (if any. )
Alternatively, a good FS Master can also use the Flying Star method to look at the the combination of the two stars and the base unit. Usually, if a certain number is in combination to make the location too `yin' e.g. at the North East location, then the chances of that either something previously had happened there or chances are, your Chinese Loupan will detect some haunting activity!
I will go into the Flying Star method in another one of my tips!
