Turtle Underwater Live WP description

Turtle in Feng Shui is considered a symbol of longevity, wisdom, protection and health. Feng Shui is the four celestial animals, and so, the turtle is one of such animals. In the teachings of Feng Shui is believed that the turtle should be in every home, and if there is a turtle, then the "back" of each house must be "turtle". That is, each house must be some excitement or any building more than your house.
Buildings that do not have protection for the "back" are considered unsuccessful. In the old days in China for a long time people chose the area to build a house.
Protecting behind should be always, even when you're sitting at the dinner table. Try to sit so that your back by always had some support.
