The word "water" for the Chinese people symbolizes both wealth and prosperity.

This door pull with its form originating from the Chinese  character "water" builds on this ancient belief of "Feng Shui" where water means money and if placed at the entrance would bring wealth to the owner of the house

Another feature of this door pull is its built-in lighting which guides people to the door in a dark room

On cold nights, the heat from the light would provide some warmth to the people opening the door (play of words : a warm welcome)
On foggy nights, it would form interesting light rays through specially cut holes/slots.
