What is the Three Killings and how to deal with it?
The Three Killing or “San Sha” is a set of three inauspicious energy or qi that afflict certain sectors of a house each year.
The three inauspicious sha are Robbery Sha, Disaster Sha and Year Sha.
The sectors afflicted by Three Killings is dependent on the animal zodiac sign of the year. For example, Three Killings afflict the North sectors in the year of the Tiger, Horse and Dog. It affects the South sectors during the years of the Monkey, Rat and Dragon and so on.
The table below shows that the sector or mountains affected by the three shas in each year.
| Year | Robbery Sha | Disaster Sha | Year Sha |
| Tiger, Horse, Dog | NW3 | N2 | NE1 |
| Snake, Rooster, Ox | NE1 | E2 | SE3 |
| Monkey, Rat, Dragon | SE3 | S2 | SW1 |
| Pig, Rabbit, Goat | SW3 | W2 | NW1 |
Referring to the 24 mountains, you can see that the three afflicted mountains in each year, sandwich two other mountains. For example in the year of the Tiger, Horse or Dog, the afflicted mountains NW3, N2 and NE1 sandwich N1 and N3. These two mountains are called “Squeezed Mountains” and are afflicted to some extend.
Therefore, in practice, during the year of the Tiger, Horse or Dog, Three Killings afflicted the entire north sector and NW3 and NE1, a span of 75 degrees. And in the year of the Monkey, Rat and Dragon, Three Killings include the entire south sectors of S1, S2 and S3 plus the neighbouring SE3 and SW1.
The best way to avoid the negative effect of the Three Killings is to restrict construction works such as digging and demolition in the afflicted area during that year.
The penalties for violating Three Killings are as the name imply are robbery and injuries arising from it, natural disasters, accidents, illness, obstacles etc.
Some masters suggest putting live plants in the area affected by Three Killings to diminish its negative effect. For me, no major renovation in the affected area is sufficient!
Another important thing to avoid is carrying out major renovation in the house, if it sits on Three Killings. For example if you house sits on NW3, N1, N2, N3 or NE1, you should avoid renovating completely, during the year of the Tiger, Horse or Dog,
This apply to houses that are currently tenanted. It does not apply to renovating new or vacant houses.
