Right in the middle (between. Heaven and Earth, and the other elements) is earth. Its days are Wu and ji. Its divine ruler is Huang Di, and the (attending) spirit is Hou-tu. Its creature is that without any natural covering but the skin. Its musical note is Gong, and its pitch-tube gives the gong note from the tube Huang Zhong. Its number is five. Its taste is sweet. Its smell is fragrant. Its sacrifice is that of the middle court; and of the parts of the victim the heart has the foremost place. |
