People in Hong Kong believe that dragons live in the mountains and hold positive and powerful energy. This energy blows through Hong Kong daily as the dragons make their way from the mountains to the sea to drink and bathe.
As Hong Kong expands, builders and architects create massive structures that potentially “block” the dragons’ passage from the hills to the sea, creating bad feng shui and blocking the natural air flow through the city. Thus, architects plan housing and office complexes with “gates” or “windows” allowing dragons to pass through the city unimpeded on their way to the sea.
I am not saying that Feng shui is superstition but I feel creating a hole in between buildings for dragons is way beyond superstition.
