I made this piece of craft with quilling paper. This is known as Yin and Yang , a Chinese symbol originated in 3rd century B.C(or even before), which has its roots in Taoism. YIN is the black side with a white dot and YANG is the white side with a black dot in it .In Chinese philosophy , it has many meanings ,one of which is the concept of balancing bad and good .YIN is the dark/bad side and YANG is the bright/good side. This symbol simply shows us the balance of bad and good in everything ,i.e, bad always has good in it and good always has bad in it ,and they are dependent on each other(two sides of the same coin). In YIN lies YANG and in YANG lies YIN. This symbol altogether represents life.
