Other types of Sha Qi or poison arrows

[Cecil Lee]

1. Neighbor's triangle shaped roof that is aimed towards your home or apartment at the same LEVEL. For example, if the neighbor's roof is equivalent to your unit at say 4th storey, if one stands inside your home and at the parallel, can see the pointed roof; then this is sha qi.

2. Another most common is the "porcupine" spikes of neighboring stacks that slices towards your stack: from the same block or neighboring block.
