The design concept follows the theme of ‘The Circle of Life’ and yin yang

In eastern thought, the two complementary forces that make up all aspects of phenomena of life.

Yin is the symbol of earth, femaleness, darkness, passivity and absorption. It is present in even numbers, in valley and streams, and is represented by the tiger, the colour orange and a broken line.

Yang is conceived of as heaven, maleness, light, activity and penetration. It is present in odd numbers, in mountains and is represented by the dragon, the colour azure and an unbroken line.

The two are both said to proceed from the Great Ultimate (Taiji), their interplay on one another (as one increases the other decreases) being a description of the actual process of the universe and all that is in it.

In harmony, the two are depicted as the light and dark halves of a circle.

The concept of yin yang is associated with the idea of five phases
metal / wood / water / fire / earth
