Dear Master Lee, I have placed an eight hollow metalrod windchime in my master bedroom window for some months. I realise the window is at the northwest side of our bedroom, though facing west.Our bedroom is in the northwest side of the house. From our bazi, I found that my husband, daughter & I (sharing)are in east group.Initially, we have it for the beautiful sound. I wonder will it affect us? Thanks. Yours, Anon
