The interior and the treatments are largely based on the taoistic philosophy of the 5 elements.
wood,fire,earth,metal and water.
This philosophy was the explanation in the old China for the holistic and cyclostic link between nature and man.
EVERYTHING IS CONNECTED AND EVERYTHING RETURNS
The water let’s the forest grow,the forest supplies the wood which makes the fire burn.
This turns into ashes, which creates a fertile earth, the earth forms the metals and metal oxidases because of the water.
Water is the beginning and the end.
