Yin-Yang is an ancient Chinese philosophy of balance, life harmony, and vital energy. It originated in China but was transmitted to Japan via China and Korea around 1500 years ago. Yin-Yang is often described as a concept of dualism, how seemingly opposite forces may actually be complementary, interconnected, and independent in the natural world. We changed this philosophy just a little and now it is the balance of love in our fanart Yin-Yang Heart Sticker.
