Wei Zhao, a historian of the Han Dynasty, wrote in Guoyu Zhengyu: "Peng Zu, Dapeng also." Dapeng here refers to Peng Guo, also known as Dapeng Guo. Established under the leadership of Peng Zu, the leader of the Peng tribe, the Xia Dynasty was a relatively strong and closely related subordinate state. King Qi of Xia had ordered King Shou of Dapeng to put down the Xihe rebellion. The early Shang Dynasty was also very strong. When the Shang King was a foreign ruler, he helped to settle the rebellion of Shao people and Hu people. In the Spring and Autumn Period, the historian of Jin State and the historian of Wei State in the Warring States Period wrote The Year of Bamboo Books: "In forty-three years, Wang Shi defeated Dapeng." So Dapeng State has existed for about 800 years. This may also be the origin of Peng Zu’s 800-year-old life.
There are many records in the oracle bone inscriptions unearthed from Yin Ruins, which not only confirm the authenticity of the records of Dapeng State in the historical books, but also trace the history of the written records of Peng State to more than 3200 years ago. There are still many sites to be found in Pengguo in Shang Dynasty.
According to documentary records, Tongshan District of Xuzhou City, Jiangsu Province was once known as Pengcheng, the earliest enclave and birthplace of Dapeng State. Many ancient sites have been discovered in Xuzhou area, which also confirms the existence of Dapengguo.
According to the textual research of unearthed cultural relics, Dapeng State should be established on the basis of the tribal alliance in Longshan Culture Period. Rapid development and strong national strength. He helped Xia Ping to settle the Wuguan rebellion of Xihe River, and helped the businessman to suppress the rebellion of Shao Ren. Xuzhou is the birthplace of Dapeng State, and Dapeng Village is the birthplace of Dapeng State.
