陰 - Yin1 - Shady, Cloudy, Secret, Feminine

This is the famous 陰 of 陰 and 陽 - Yang2 - Sun, Masculine.

This is related to the five elements stuff I mentioned before. I don’t pretend to understand any of it. I only mention it because today we went to see this Japanese movie, 陰陽師 - Yin1 Yang2 Shi1 - Yin Yang Master. In Japanese this is apparently pronounced Onmyoji.
