"Shiben·Ju Pian" states: "Zhongshan Wu Gong lived in Gu, and Huan Gong moved to Lingshou ." Lingshou City, where Huan Gong lived, has been confirmed to be located in the northwest of Lingshou County, Hebei Province after archaeological excavations in the 1970s. 10 kilometers away is the area of ​​today's Sanji Township in Pingshan County. However, there are two main opinions about the location of Gucheng, where Wugong lived in Zhongshan, Dingzhou and Tang County.

The first is the Dingzhou theory. Because the Zhongshan Kingdom of China, which was entrusted by the four dynasties of Han, Wei, and Jin, was ruled by Dingzhou City in today's China. Therefore, it has long been believed that Gucheng was Lunu (now Dingzhou City) in the Han Dynasty. For example, Gao You of the Eastern Han Dynasty said, "Zhongshan, the capital of Di, is now Lunu Zhongshan." This actually means that Zhongshan once established its capital, Gucheng, in Lunudingzhou.

The second is the Tang County theory. Tang County has Zhongren and Zuoren, important cities of the Spring and Autumn Xianyu Kingdom. Because many scholars believe that Zhongshan is of the same origin as the Xianyu Kingdom, they believe that Zhongren City is the capital of Zhongshan. The Western Jin Dynasty Zhang Yao's "Zhongshan Ji" It is believed that "there are mountains in the city, so it is called Zhongshan". Northern Wei Li Daoyuan also thought that Zhongshan during the reign of Duke Wu should be in Zhongren City. It is said that "there is a hill in the city, which rises sharply on the west side of the city, and looks like Weisu Yan." It is suspected that "Tundao Ji" says Wangdu County has Weisuguan Pass. It is said that the mountain is in the city, so it is also called Zhongshan City ". Most of the geographical works of the Tang and Song dynasties, such as " Kuo Di Zhi ", " Taiping Huanyu Ji " and later, followed this view. This view holds that Gucheng is located in today's Tang County.

"Baoding County Chronicles" clearly records that Zhongshan Wu Gong was granted a title in Qingdu, and the earliest annotation of Gu Ji Dingzhou is Jin Du Yu. Because Tang County was under the jurisdiction of Dingzhou during the Jin Dynasty, later generations used it to steal the beams and replace them, and the Historically, Dading Prefecture is confused with present-day Dingzhou City, ignoring the fact that Zhongshan County was governed in Zhongshan City, Tang County in the early Han Dynasty, and Liu Sheng was granted the title of Queen Zhongshan and moved the county out of the mountain to Lunu. In addition, in 414 BC, Wu Gong was first established. , was taken out of context by some scholars as the beginning of the founding of Zhongshan, resulting in the erroneous conclusion that both Han Zhongshan and Warring States Zhongshan were located in today's Dingzhou City. In the fifth year of Taihe (AD 384), Emperor Xiaowu of Jin Dynasty, Murong Chui established the capital in Zhongshan City, Tang County. Later Yan changed the Yuan Dynasty to Jianxing, and later moved the capital to Dingzhou. The true history has also been ignored by some people, in order to directly establish the capital. In his account of Dingzhou, the fact that Tang County is not mentioned is an attempt to whitewash the local culture's struggle for historical resources and disrespect the historical truth.

Professor He Yanjie of Hebei Normal University, author of "History of the Zhongshan Kingdom in Xianxianyu", believes that Gu is more accurate in Tang County. Because Tang County was under the jurisdiction of Dingzhou for most of its history, except for the jurisdiction of Baoding , the rest of the time Tang County was under the jurisdiction of Zhongshan County in the early Han Dynasty. In the past, Zhongshan County, Zhongshan State, and Zhongshan Prefecture were all governed in Dingzhou. state. Some experts also believe that Gu only appeared once in the history books and existed for a short time. Moreover, the cultural relics of Zhongshan during the Warring States Period have not yet been excavated in Dingzhou City, and their exact location has not been clarified. Most of them are generally described as being in today's Dingzhou City. The Five Dynasties After Liang Kaiping for three years (909 AD) Shi Jingtang rebelled against Tang and established the country. On the grounds that Tang County was the hometown of Zhongshan Kingdom, he overthrew the original name and changed Tang County to Zhongshan County. Fourteen years later Li Cunxu restored the country after its restoration. It is called Tang County. In the Song Dynasty and later, some ancient literati wrote about Zhongshan in their works, and wrote poems about Wesu Mountain, Beitai, Niliuhe and other places in Tang County. These works were included in the Zhongshan culture of today's Dingzhou.

To sum up, Gu Diwang is historically accurate in Tang County.
