From "City Chronicle" to "Yao Feng ShunYu: Yuan Dadu Planning Thought and Ancient China", Wang Jun has gone through a process of twenty years of research and exploration. From a senior reporter of Xinhua News Agency, deputy editor-in-chief of The Outlook News Weekly to a research librarian at the Palace Museum, Wang Jun has chosen to trace the origins of Chinese civilization and constantly inquire about the value and significance of traditional Chinese culture. After reading a large number of ancient documents and archaeological reports, making one or two million words of reading notes and doing a lot of research and mapping, he took Qi Zhenglou and Yuan Dadu as the starting point and dedicated a weighty work to the academic community and the majority of readers.
The recently published "Yao Feng ShunYu: The Planning Thought of the Yuan Dynasty and Ancient China", the whole book is divided into two parts, A is "Qi Zheng Lou Name Orientation Examination", the original meaning of the name of the Qi Zheng Lou, the construction site of the Qi Zheng Lou and the Bell Tower discussed by the academic community for many years, and at the same time examines the architectural nature and construction site of the central pavilion and the central platform of the Yuan Dadu Datianshou Wanning Temple, and studies the central axis system of the Yuan Capital, revealing the significance of Kublai Khan's taking the meaning of "Shangshu YaoDian" to name Qi Zheng Lou; The Yin-Yang French Style of Yuan Dadu Planning takes the planning and architectural layout of the big city of Yuan Dadu as the research object, combined with the study of ancient Chinese astronomical laws and calendars, and reveals the Yin-Yang French style and ideological concepts it contains.

Where was the Qi Zheng Building in Yuan Dadu built?
"Yao Feng Shun Yu" conducts in-depth research on major issues in the central axis system of the Yuan Capital, which has long been divided in the academic community, with detailed historical research and on-site investigation, and draws clear conclusions.
Among them, it is confirmed that the central axis of the Yuan Dadu and the central axis of Beijing in the Ming and Qing Dynasties are the same axis, and the northern end of the central axis of the Yuan Dadu is the Qi Zheng Lou and the Bell Tower, not the central pavilion of the Great Tianshou Wanning Temple; the central pavilion of the Great Tianshou Wanning Temple is the divine palace of Yuan Chengzong and Yuan NingZong, located on the east side of the north end of the central axis of the Yuan Dadu; the central platform of the Yuan Dadu is not a sign of the geometric center of the whole city or the northern end of the central axis, but is built in the Yuan Dadu Jintaifang to take the righteous lixian and symbolize the golden platform; the central axis of the Yuan Dadu corresponds to the North Pole Xuanjie with the Qi Zheng Building. Taking the Yige Dao Star from Haizi Bridge, the Yi Galaxy with the Tonghui River, and the corresponding camp room star with the Yuan Danei, forming an urban landscape similar to the Qin capital Xianyang of the "Tianji Pavilion Dao Absolute Han Arrival Room"; Qi Zhenglou took the allusion of shun's mandate of heaven in the "Shang Shu Yao Dian" shun's mandate of heaven "In Xuanjie Yuheng with Qi Qi's seven governments", thus showing that Kublai Khan was a descendant of Yao Shun, and the Yuan Dynasty was Chinese orthodoxy, which was of great significance in the development process of the unification of the multi-ethnic state in ancient China.
Relevant experts believe that these studies are of great significance to understanding the central axis system of ancient Chinese cities and the historical and cultural value of Beijing's central axis.
What is the cultural "gene" of the ancient Chinese construction system?
"In the course of my research, I was amazed time and time again at the layout of the Yuan Dynasty, a considerable part of which still exists in today's Beijing, so precisely and artistically carrying the most central knowledge and ideological system of ancient Chinese culture," Wang said.
Based on ancient documents and archaeological data, Yao Feng Shun Yu systematically reveals the ideological system on which the planning and design of the Yuan Capital is based. These include the profound connection between the time-space pattern of the Meridian Unitary of the Yuan Dadu and the farming culture, the profound influence of Yixue Thought on the layout of the Yuan Dadu, the astronomical significance of the Jiande Gate of the Yuan Dadu and the An Zhenmen taking the meaning of "Zhou Yi" Qiankun Erkun, and the embodiment of Jiaotai Thought in the urban planning of the Yuan Dadu.
It is worth mentioning that this book also compares the planning and design of the Yuan Capital with the ancient capitals of Han Chang'an, Sui, Tang, Chang'an, Ming and Qing Dynasties, and beijing, and draws a clear conclusion: the concept of time and space closely combined with the activity of visual time-teaching profoundly defines the ancient Chinese construction system, and space is given meaning by time, becoming the carrier of knowledge and ideas, and shaping the architectural form generated with the environment of heaven and earth as a whole. Several of the proportions of heaven and earth used in the ancient Chinese construction system have exact cultural significance. Therefore, the study of ancient Chinese architecture, in addition to the investigation of structural technology, must also be combined with the study of mathematics to deeply reveal its cultural "genes".
