WHAT ARE THE GREEN LINES FOR?

We technically entered the Monkey Year on February 4th 2016.  This means that the Flying Stars have settled comfortably in their new sectors in the house.  I have been redoing the Feng Shui for my house since before the fourth. I am still working to fine tune the remedies and cures.
In the pictures above, you can see that I have divided my house into the sectors.  I used green tape to mark the sectors.  Hopefully I will be able to complete the job by next week.
