I read ona few websites that the items for fengshui needs to be cleansed, how doI do it? Also,there are differing opinions about where to place the3 chi lins, some say outside, while others say just inside thedoor - facingthe directions of the 3 killings. Can you please tellme what is correct? Also, with the wind chime, some say 6 metals rods and wood for other parts is better than all metal. Please also enlighten. Thank you.
