Duke of Zhou is a fake book.

The so-called fake book means that the real author of the book is different from the author of the annotation, and the real compilation time of the book is different from the compilation time of the annotation. In fact, it has long been concluded that Shangshu, an ancient Chinese prose, is a fake book, and the appearance of Tsinghua bamboo slips is only the last nail in this coffin. As for the popular ancient prose Shangshu, is it still valuable? From the perspective of historical value, fake books can be said to have no historical value at all. For example, the dialogue between Zhou Wuwang and Ji Zi described in Hong Fan Pian in China's ancient book Shangshu mentioned five elements: "One is water, the other is fire, the third is wood, the fourth is gold, and the fifth is earth. Moisturizing, fire inflammation, straight wood, golden leather, soil fertilizer. Moisturizing the bottom is salty, burning the top is bitter, correcting the truth is sour, making the leather pungent and cultivating the crops sweet ",which has always been regarded as the evidence that" the five elements originated in the Western Zhou Dynasty ". Shangshu, an ancient prose handed down from ancient times, has been proved to be a fake book, so its description of Jin Mu's five elements of fire, water and soil has no historical value and can no longer be used as evidence that the five elements originated in the Western Zhou Dynasty. But the fake book was written by the ancients after all, and it bears the imprint of the forger era. It is still valuable to study China's academic forgery history or publish it.
