Don't assume that it is a poison arrow: Check it!

[Cecil Lee]

1. Under Shapes and Forms Feng Shui; it is best that there is no Sha Qi (poison arrow[s]) aimed towards the main entrance door.
2. In this illustration, just because it appears that there is a poison arrow of the 90 degree angle of a corridor wall; it does not necessarily mean that there is a poison arrow. Here, go and check it out!
3. The best way is to LOOK AT THE FLOOR TILES andfollow the imaginary line at 45 degress angle and see if it lands anywhere close to the main entrance door or not?
4. In this example; @ Blk 288A, Punggol Arcadia, fortunately, stack 809 is safe from the perceived "poison arrow".
5. If one follows the YELLOW line on two of the attached photos; the line does not cut into the main entrance door nor the grill gate.
