flying star for business esp southeast sector

Dear Robert and Cecil,
I just ran a flying star report for my gas station. The Southeast sector concerns me because that's where my convenient store, half of the front door to the gas station and my cash register are located.
In the Southeast sector, the 20-year star (star 5) vs. the year star (also star 5) which form an inauspicious combination and the solution is to use METAL to exhaust and weaken earth. The mountain star (star 8) vs. water star (star 4) also form an inauspicious combination and the proposed solution is to use METAL to destroy and control wood.
Is it OK if I hang a 6-hollow rod metal windchime outside the front door AND a 6-coin-tied-with-red-string above my cash register to neutralize all the badness described above?
In the South sector where my mechanics work, the mountain star (star 3) vs. water star (star 9) also form an insauspicious combination. The proposed solution is to use FIRE to exhaust and weaken wood. What does this mean? What is considered a fire solution?
Thank you so much as always,
hoa
