Shuangzhong Ruins

　　The Shuangzhong Ruins are situated on the northern side of Shuangzhong Village in Wangdian Township, southeast of the county town, approximately 1.5 kilometers north of the Pingliangtai Ancient City site and adjacent to the Cai River to the east. This is an area that includes cultural remains from the Longshan, Erlitou, and Shang dynasties. It was designated as a county-level cultural heritage protection unit in 1962.

　　Currently, the two mounds are 20 meters and 16 meters high respectively, covering an area of about 5,740 square meters, and were built with rammed earth. Beneath the mounds lies a broad ancient cultural site spanning approximately 52,800 square meters, with an average cultural layer depth of around 5 meters. The site contains a wealth of relics, including red-fired earthen house foundations to the southeast of the mounds. It is a site of an ancient settlement that was densely populated and relatively large in scale.

　　After 1972, artifacts unearthed at the site include pottery spinning whorls, pottery net sinkers, stone shovels, stone axes, and stone adzes. A large number of deer antlers, clam shells, and the bones of pigs, sheep, dogs, and cattle have also been found. Identifiable pottery fragments include: bowl-shaped tripods and flared-rim vessels from the Longshan culture period; tripods and other vessels from the Erlitou culture period; and large-mouthed zun vessels and flared-rim jars from the Shang dynasty.

　　The "Huaiyang County Annals" from the fifth year of the Republic of China (1916) recorded: “The Shuangzhong Mounds are twelve li southeast of the city, with two connected mounds standing about six or seven zhang tall. During the Spring and Autumn Period, a daughter of the Chen State married Duke Zhuang of Wei and gave birth to Prince Xiaobo, who died young. Her younger sister, Dai Gui, bore Duke Huan, while a favored concubine gave birth to Prince Zhouxu. After Duke Zhuang died, Duke Huan ascended the throne, but Prince Zhouxu killed him and declared himself ruler. The two sisters of Gui returned to Chen, where they eventually died and were buried here.” Hence the name Shuangzhong (Double Mounds).
