前人对《周易·革》卦“己日”的解释有三种,其中,认为“己”为天干纪日的说法是正确的。但是对于选择在己日进行变革的原因,解释得不准确。己日位于天干的第六位,六在上古时代,有特定含义,象征事物发展的极端状态。这在《周易》中可以看得很明显。因而,“己日”表示某一阶段的终结,物极则反,含有变革的意味。 There are three kinds of explanations by predecessors to the “Gu Yi” of the “Guiyi and Gui” in the Book of Changes. Among them, the view that “one’s own” is the Goddess of Mercy and Diary is correct. But the reasons for choosing to make changes in the past are not accurate. The sixth day of the Heavenly Stem has been the sixth, six in ancient times, have a specific meaning, a symbol of the extreme state of things. This can be seen clearly in the Book of Changes. Therefore, “our own country” means the end of a certain phase, the opposite of materialism and the meaning of change.
