Dear Cecil, I have a 4m 7b 8w combination at the front door and I am so very confused as to what to activate. I have read Eva Wongs book and she says that I should concentrate on relationship between 7b and 8w. However, Stephen Skinner says that 4m and 8w should be concentrated on? As it is an 8 period I understand that at my front door this is extremely beneficial and want to make most use of this. Please inform me if I need fire energy inside the house and whether I require water outside to activate it or is a quiet road ok as active chi? Thank You for your help.
