Sorry. I always type like that.

I have a question since you have studied this area over 20 years, what does one do when the front door to the apartment is not the door used for everyday entering? I have not used my front door in over two years. It was my understanding that chi comes in when the door is opened - the most frequesnt door used. I based the information on this. My front door does not have a left side, it is the wall of the entire apartment. Please help me with these concerns.
