《晋书·志·第二章》
月亮是太阴的精华，用它来匹配太阳，是女主的象徵；用它来比拟德行，表现了刑罚的意义；排列于朝廷之上，属于诸侯大臣之类。
月为太阴之精，以之配日，女主之象；以之比德，刑罚之义；列之朝廷，诸侯大臣之类。
The moon is the essence of the yin, matching it with the sun, it is the symbol of the mistress; using it to compare virtue, it shows the meaning of punishment; arranging it in the court, it belongs to the category of feudal ministers.
