Puyang was called the Mausoleum in ancient times. According to legend, Zhuan Xu, one of the five emperors, once used it as the capital, so it has the reputation of an imperial city. The name of Puyang began in the Warring States period, and it was named because it was located in the yang of Pushui (a tributary of the Yellow River and Jishui, which was later silted up by the Yellow River). It is one of the important birthplaces of ancient civilization in China. 1986, typical artifacts of Peiligang culture, such as stone mill, stone roller and three-legged pottery, were unearthed in China, which proved that there were human activities here seven or eight thousand years ago. 1987, three groups of dragon and tiger tombs built by mussels were excavated in Xishuipo, Puyang. According to the determination, its age was about 6,400 years ago, and the clam shell dragon was recognized as the "China Yilong" by the archaeological community. Experts infer from this site that Puyang took the lead in entering the patriarchal society 6000 years ago and became the birthplace of Chinese dragon culture. Puyang was named "loong Township" by Chinese Yanhuang Culture Research Association.
