On the Original Meaning of "the Three Rights" and "the Five Elements"--Also Some Problems in Ancient History

The five elements are the five periods of the rise and fall of Yin and Yang.It was the necessary element to make the ancient calender.The three rights are the means to define the first day of a year in which the heaven,earth and human beings were regarded as the reference frame.If the persons to make the calender wanted to work out an almanac that accorded with the regularity of human activities,they must grasp the theory of the three rights and the five elements.The Oath of Gan coming from what was written down by the history officials of the Xia Dynasty is not false.The change of the first day of a year and the colour of the clothes had no relation with the distortion of history.The possibility that Liu Xin fabricated the ancient history can be ruled out.
