The Wu Lou (Calabash) in its original form is a fruit and when dried was traditionally used to store medicine or water which is is how it got its name “giver of life”.
The shape of the Calabash was replicated into brass (metal weakens earth) by Feng Shui masters many years ago in order to absorb the negative energy of the bad luck stars.
The five emperior coins have strong energy in feng shui for good luck prosper wealth and money back!
