On November 9, 2000 (October 14, 2000 in the lunar calendar), the "Chronology of Xia, Shang and Zhou" was officially announced. After five years of hard work by more than 200 experts and scholars, the Xia, Shang and Zhou dynasties, which traced the origin of China civilization and traced the direction of China civilization, finally had a relatively clear chronology standard. On November 9, 2000, the "Xia, Shang and Zhou Chronology" officially announced the "Xia, Shang and Zhou Chronology", which extended my country's historical chronology from the first year of Gonghe in the late Western Zhou Dynasty, that is, 841 BC, to more than 1200 years, making up for a major shortcoming in the study of ancient civilization in China. Chinese civilization is one of the universally recognized civilizations, and it is the only civilization in the world that has been continuously transmitted without interruption. However, the Xia, Shang and Zhou dynasties, which marked the rise to prosperity of Chinese civilization, have been everlasting and have become a major shortcoming in China history and world history. This "Chronology of Xia, Shang and Zhou", completed at the turn of the century, has made huge and solid efforts to fill the gap in our country's ancient chronology. According to this chronology, the beginning of the Xia Dynasty in my country was about 2070 BC; the boundary between Xia and Shang Dynasties was about 1600 BC; the migration of Pangeng to Yin Dynasty was about 1300 BC; The boundary between the Shang and Zhou Dynasties was 1046 BC. The chronology also lists the specific years of the reign of the 10 kings of the Western Zhou Dynasty, and lists the approximate years of the reign of the 12 kings from Pangeng to Emperor Xin (Zhou) in the late Shang Dynasty. Li Xueqin, chief scientist of the Xia, Shang and Zhou Dating Project, said at today's press conference that the "Xia, Shang and Zhou Dating Project", a key scientific and technological research project launched in May 1996, has dealt with the historical problems of scholars in successive dynasties since the Western Han Dynasty. It has hit the historical problem. Over the past five years, this project has gathered more than 200 old, middle-aged and middle-aged experts and scholars in disciplines such as history, archaeology, astronomy, and scientific and technological dating in our country. In accordance with the requirements of systematic engineering, 9 topics and 44 special topics have been set up. Comprehensive and new research and textual research on chronology issues in the Xia, Shang and Zhou dynasties have been carried out from different angles, different aspects, and different methods. Different from the traditional chronology research institutes for more than a thousand years in the past, this project adopts a multi-disciplinary joint research and cross-research method, especially for those eras that are highly controversial and crucial to the entire dating framework. A very cautious attitude is adopted and the conclusions are strived to be supported by multiple clues and multiple angles. In September 2000, on the basis of passing the acceptance of each topic, the "Xia, Shang and Zhou Dating Project" proposed that the "Xia, Shang and Zhou Chronology" and the "Xia, Shang and Zhou Chronology Report on the Phased 1996-2000 Achievements of the Xia, Zhou Dating Project" were supported by multidisciplinary research results, met as many conditions as possible, and were consistent with relevant data as possible, and were mutually consistent with each other in various historical stages, and passed the national acceptance. The engineering expert group and the engineering acceptance team believe that this is by far the "most scientifically based" chronology of the Xia, Shang and Zhou Dynasties. It is the best achievement that can be achieved under current conditions and represents the highest level of chronological research. Professor Li Boqian, Professor Qiu Shihua, Chief Scientists of the Xia-Shang-Zhou Dating Project, Academician Xi Zezong and other members of the expert group also attended today's press conference. They said that the chronology is only a phased achievement and needs to be improved and refined. In the future, with updated archaeological discoveries and research will be further corrected and adjusted.
