Is 9 gold coins tied with a string used to cure the bad stars #2 and #5? You recommended before 6 gold coins tied with a string. An FS expert says that 9 coins is good too as well as 6 coins. What is your recommendation?

Under the Flying Star Feng Shui, #9 represents the fire element.

And fire inflames #2 (bad - weak - earth) and #5 (bad strong earth) elements. Not exactly the kind of cure one should intend to apply to these two bad earth stars. Maybe, just maybe for #3 (bad wood).

In my opinion, therefore, it is not the normal convention to apply 9 coins for #2 and/or #5. However, as Flying Star analysis takes into account the 81 combinations of the Mountain and Water Stars, then in some cases, it may be used.
