As some scholars have described more than three generations the true extent of the ancient literature and include Yu Sovereigns and Five Emperors, including whether there are per capita real challenge, "Yangcheng" The location is in Dengfeng and "Da" whether there is a real person, We can have a relationship with each other to prove. In other words, to prove that "Yangcheng" indeed as ancient literature, in the "Songshan Yang, Yin Jishan", we can have it Dayu real people to give evidence. The "Yudu Yang City" is indeed "Songshan Yang, Yin Jishan" in the town of Dengfeng City, Gaocheng Wangchenggang ruins of archaeological excavations, is constantly testament.

50s of last century, the famous archaeologist Mr. Xu Xusheng find out about the ancient books from the pre-Qin Xia Dynasty and contains the names of about 80 historical, remove duplicate, leaving about 70. The results of his exploration, there are two areas that should be of particular concern: First, Luoyang plains, especially water Ying valley upstream Dengfeng, Yuzhou area; the second is downstream of Shanxi southwest fenshui area. "Yu Juyang City", "Yudu Yang City" literature has contained, but there are two in Henan Yangcheng said that in Shanxi also has two says, and "Historical Records family · Han Zheng family" and "Six table." Korean Hou in mind two years (BC 385), "Han Zheng cutting, take Yangcheng." This has a clear record of events, not only in the earliest times, but also the Yangcheng framed in Dengfeng area. Accordingly, Mr. Xu Xusheng believes Dengfeng Yangcheng Gaocheng ancient town, "is a common argument, is more correct to say." Thus, Xu Xusheng opened the China Archaeological Survey "Summer Market" Xia culture prelude archaeological research, and in 1959, on the site between the town of Dengfeng City of Henan Province Gaocheng village Plus archaeological survey found Wangchenggang site, then known as "Plus sites."

In the late 1970s by archaeologists in the "Octagon site" found a Henan late Longshan culture small city site, the foundation pit, bronze pieces and text, and in accordance with customary title of local people, which was named "Wangchenggang site" . Yangcheng era on Wangchenggang ruins and documented, relatively consistent position disputed city site was found too small, and Yu is not proportionate. As the "Origin of Chinese civilization pre-project research" a major research topic, from 2002 to 2005, the School of Archaeology and Museology and Henan Institute of Cultural Relics and Archaeology of Henan ruins Wangchenggang late Longshan culture city site and surrounding investigation, drilling and to explore the newly discovered an area of ​​about 300,000 square meters of large urban sites. Materials from the current look, with the original town site was found with the late Longshan culture of Henan, has a little time to build the city, is the year of the largest ever found in the ancient city. Away from the walls and moats very close to the bone was found buried in burial pits at the bottom of the moat found skulls for ritual, and the user is able to reflect the identity of jade Cong and white pottery relics of high-specification, all illustrate this One site is one of the important centers of the Central Plains region of ancient settlement.

Ayutthaya found it in time, place, scale of qualified called Yudu, there are more and more recognized experts Yudu possibility of Wangchenggang. Archaeology and Museology, Peking University professor and doctoral supervisor, said Liu Xu, Wangchenggang in early summer to explore the important role of culture in the academic consensus, as is generally believed that Yu Xia Dynasty is the first monarch, if one day be able to confirm that Yudu Yang Wangchenggang the city, the mystery of the origin of summer culture will be solved, and the late Longshan culture academics argue over whether ending this summer on behalf of early archaeological culture.

On the construction of the waste Wangchenggang Ayutthaya, experts say, may be the largest city in the East after the town was built in the floods, 4,000 years ago in China, may have occurred many years of an ongoing flood disaster, that big flood, perhaps, the rule of the legendary Yu water. Some scholars speculate that Ayutthaya north moat extends eastward to the town Wangchenggang envelope which Wangchenggang Miyagi or ancestral temple town when the boat lies the big city, "Yangcheng" in Dengfeng Wangchenggang therefore more credible.

Xia Dynasty history to understand the people know that the Xia Dynasty moved the capital to very frequent. Between son Kai Shun Yu's son beneficial competition for top leadership, the occurrence of war, Wangchenggang cities may therefore be destroyed, this may be the reason XIA Qi moving the capital. Moreover, we want to commemorate Dayu, verify that the "Yangcheng" orientation, so that later other large city site of the Xia Dynasty discovered early, and can not shake Wangchenggang site as "Yangcheng" status. Even when then Wangchenggang town early discovery, its as Yudu qualifications expressed doubts Mr. famous scholar Xu Shun Zhan, also Wangchenggang cities found later changed his mind: "(Wangchenggang Ayutthaya) may be the initial Gun, Yu and Kai capital. "

Go back and look in the records of ancient literature, not only Yudu Yang in Dengfeng city, was later moved the capital XIA Qi, Tai moved the capital, also are in the Songshan Mountain, after all, the founder of the Xia Dynasty started in Song Yu on Yue of the land!

To demonstrate to Wangchenggang where excavation results, in Gaocheng Town Dengfeng City, Henan Institute of Cultural Relics adjacent to the west of the original scenic Dengfeng Observatory at the workstation, set up a museum of ancient Yangcheng, the main display Wangchenggang Yangcheng sites and unearthed relics, including the Xia Dynasty to the Eastern Zhou Dynasty when the stone, pottery, bone, bronze and so on.
