Would like to have your advice as my kua no is 4 and the house that I bought recently is facing the worst direction ie. northeast (chueh ming).
I am not sure whether if have checked out all the other directions of your house in relation to e.g. the 8 house theory. More importantly, look at areas where you spent most of your time e.g. your bedroom. Check to see whether the intangible force `lands' over this area.
For the worst direction i.e. North-East, this is also considered the Devil's Main entrance. I not sure if you have already read the short article I wrote regarding this topic. If not, please check out Devil's Gate
Briefly, avoid planting too many plants outside the North-East and especially the South-West (which is considered the devil's backdoor). The rationale for this is because especially large plants are `target' of spirits who could take the opportunity to `hide' there.
Since your door is at the North-East, the best advice is not to open the door unless you are using it.
There are a few `cures' available for this and I have already documented it. You could perhaps read this reply: Click here which can help you.
