Actually, we can apply the feng shui theory in a modern way instead of the old application. I remember I went to Brunei for feng shui audit many years ago for a Malay lawyer. (Again, I want to stress again here that feng shui is not a religion, it is an environmental science as I went to Dubai for feng shui audit before for a Royal Prince of Arab Saudi.) Due to the fact, we could not apply the old concept by placing 5 Chinese old coins in her law firm, I taught her to put 5 metal clocks in the area of the most inauspicious star 5 YELLOW. This is because her customers base are in different countries which have different time zone.
风水其实可以活学活用, 不必跟着古老的办法来应用，但是以前的方法其实也有它的用意， 我们不可以完全否认。Feng Shui does not have to be applied in the old way, but the previous method actually has its intention. We cannot completely deny it.
Of course, the energy from the 5 Chinese ancient old coins will be much significant than the 5 metal clocks but I have mentioned many times, we cannot be greedy and want everything to be 100% prefect as there is no 100% perfect in this world. There is time we need to sacrifice for a bigger picture. I have been to many multi national companies and many well known company offices like banks for feng shui audits and they cannot display those feng shui items in their offices, I NEED TO LOOK FOR THE REPLACEMENT.
This is an useful table to describe how to apply the 5 elements in a right way.
One of my regular clients applies the 6 old coins with the 6 circulate white design in his indoor garden.
These will make gold element to the sector that need gold element. They have been created by one of clients who is a real estate developer.
These roundabout design will produce lots of gold.
If certain sectors of your house or office, you have to put the gold element, you can place a picture of the Eiffel Tower which represent BIG GOLD element there.
