Somehow I didn't take a picture of the slide with the 3 Killings and couldn't find my notes from Jason's talk. So I sourced it from another Feng Shui site to share with you.

The Three Killings - is a direct translation from the Chinese ‘San Sha’. This annual affliction is mostly in the west (232.5 – 307.5). It is imperative that you do not undertake any form of noisy renovations or re-decorative work in the west part of your house or office between February 4th 2015 and February 3rd 2016. You should also not disturb the ground by digging holes, digging foundations or conduct any maintenance work with any noisy equipment in this area inside or outside your property or garden. If you have no option but to perform work in the west, it is advised that you place a 6 hollow rod metal Wind Chime in the west in 2015. Once disturbed, this affliction can bring about three types of misfortunes – financial loss, sickness and arguments. This is the worst out of all the annual afflictions and in our home and business we take this very seriously as in our 34 years’ experience with Feng Shui we have seen some pretty nasty events from this energy when disturbed.
Apart from not disturbing its ground, there are two other rules that you should follow regarding the Three Killings in 2015. Firstly, if you are moving your desk around this year, never sit with your back to this direction (west). Secondly, it is better to face (west) this direction, especially if this is one of your four favourable personal directions. If your front door faces the west in 2015, I would advise placing a pair of Fu Dogs just inside the house looking outwards as protective guardians for the year. You can also place a Ba Gua mirror outside in the west. If you have to carry out work or emergency repairs in the west during the year of the Yin Wood Goat/Sheep, you should place a six hollow metal rod wind chime between the buildings and where the work is being carried out and ideally you should contact a professional Feng Shui Consultant to select an auspicious date to start the work or you can use our Tong Shu software. - See more at: http://www.fengshuiweb.co.uk/advice/threekillings.htm#sthash.II3q901d.dpuf
