Q1. Is there a one-for-all solution that can counteract all kind of "Sha Qi"?
No, there is no one-for-all solution to counteract all kinds of Sha Qi. This will depend on how `damaging' the Sha Qi is.
I have covered quite a lot of techniques for couteract Sha Qi:-
1. Mild forms that will not affect a close-by neighbour includes:-
a. tilting the front door from an inauspicious to an auspicious direction.
b. using a specially made semi-circle carpet outside the main entrance.
c. Using a convex door (if your Building Management permits).
d. If the main entrance has steps, then use semi-circular steps.
2. More offensive forms to counteract Sha Qi include:-
a. Pakua (some pakua also comes with a picture of a door god below it).
This is acceptable.
b. Using a kitchen fork (usually aimed from a window)
c. Cannon (usually aimed from a window)
d. Placing a fish tank at the window to counteract e.g. a lone lamp post etc.
Q2. If the front main entrance door is facing a lamp post, which is what we claimed as "chuan xin sha" in feng shui, what will happen if the owner put a concave "ba gua" instead of a convex one?
For Sha Qi use a concave `pakua or ba gua' as your home will absorb even more bad influence.
