Yin Yang tattoo design. The ideograms present in the drawing are the traditional chinese characters for Yin Yang (Hànzì: 陰陽; pinyin: yīn yáng).
For more Yin Yang / chinese symbols tattoos visit my website - www.seiza.ro. If you use any of my tattoo-designs as a model / inspiration / starting-point for a tattoo you might consider sending me some photos of the tattoo once it's complete. Thank you in advance.
