"Li Zhouzhi's Local Records" records: At that time, "there were Zhenshan in Kyushu and Hengshan and Zhenshan in the north". Erya collected goodness and recorded five mountains, and called "Hengshan Mountain as Beiyue". "History of Hanshu Geography Changshan County" contains: "Hengshan North Valley," Gong Yu "out of the constant water, into the east (now Tanghe)". This record accurately explains the relationship between Hengshan Mountain in Beiyue and related rivers in Han Dynasty. The establishment of Hengshan County in Qin and Han Dynasties was named after Hengshan Mountain in Beiyue, and because of the taboo system in imperial culture, "Hengshan" was changed to "Changshan". Li Daoyuan described Hengshan Mountain in the Water Classic Note: "Hengshan Mountain is Beiyue, which is located in the northwest of Shangquyang County in Zhongshan. From northeast to southwest, it controls Yanmen Xiongguan in the west, crosses Yuan Ye in the north of Hebei in the east, connects Wutai Mountain in the south, and borders Datong Basin in the north, stretching for hundreds of miles. The ancients climbed this mountain, overlooking Hebei and Shanxi provinces, with vast mountains and rivers and a myriad of weather. " He also said: "Ancient emperors often visited Beiyue in November, and Hou Bo had Tang and Mu Yi purified themselves. King Zhao of Zhou refused to return to the expedition, and the tour was abolished. The city of Guo still followed. Qin hit the ore field, because the county and city are all singing in Sun Shan, so it is called Quyang. " According to the preface to Hengshan Mountain, "After Emperor Gao Shun Shao Yao, there were two states in Zhaoshi and two mountains in Shi Feng. If every state is built, it is considered as a state town ... ". The title of "Zhou Li" is: "Due north is called Bingzhou, and its mountain city is called Hengshan". "General Code" contains: "Twelve famous mountains were often worshipped by officials in Qin Dynasty, and the second was Mount Heng", "Twelve famous mountains were sealed by Qin Shihuang, and Mount Heng was known as the second mountain in the world". The origin of the twelve mountains in China is explained in the Geography of Han Dynasty: "In Yao Dynasty, there were twelve states in the world, and each state had a town mountain". So it is easy to understand that Hengshan is the second place here. "Da Mao Shan, the towering North Mountain" says: Mount Hengshan in history generally refers to the endless Taihang Mountain in western Hebei. Now, the mountains from Fuping County and Laiyuan County in Hebei Province to hun yuan in Shanxi Province are called Hengshan Mountains in geography. Historical records of Hengshan Mountain in Beiyue are scattered in the sea of books. Even so, there are still people looking for a needle in a haystack, who have sorted out and studied it, especially Mr. Gu's Debate on Beiyue in Qing Dynasty. "The Debate of Beiyue" points out; Study on "Yu Shu"; As for Beiyue in October; "Zhou Li": Qishan Town, Binzhou, Heng Yue; Erya: Hengshan is Beishan, referred to as Shangquyang. Although there are no traces of more than three generations, historical records show that the king of Changshan was guilty and moved away, and the son of heaven sealed his brother to be calm, in order to continue the worship of the former king, Changshan was the county. Then all the five mountains are the sons of heaven. Hanshu says: Changshan Temple is in Shangquyang. Ying Shao's "Custom Pass" said: The temple is located in Shangquyang County, Zhongshan. The Book of the Later Han Dynasty: In the spring and March of the third year, Zhang Diyuan was blessed in Zhongshan and sent envoys to worship Beiyue in Quyang. County annals: Sun Yat-sen's country has been here for a long time because Quyang is a long mountain and Hengshan is in the northwest. Shuijing Zhu refers to this temple at the foot of Hengshan Mountain. At the end of the Han Dynasty, when the world was in chaos and the mountain road was impassable, the sacrifice was made here. I don't know if the class teacher spoke first, but filial piety is too common, not at the end of Han Dynasty. Shu Wei: In the autumn and August of the fourth year of Taichang in Yuan Di in the Ming Dynasty, Wei Xin traveled eastward and sent an envoy to sacrifice Heng Yue; In the winter of the first year of Taizi Emperor Taiyan, Bingzi was fortunate. In December, Guimao's envoys worshipped Beiyue Yutai; Taiping Town Army arrived in Zhongshan in the spring of the first month of the fourth year. In February, Bingzi drove as far as the grandson of Hengshan Mountain and ordered the publication of Xeloming. November, winter, November, south expedition, through Hengshan sacrifice too fast; In the first month of the first year of peace in Wen Chengdi, thanks to Zhongshan, he crossed Heng Yue and returned to God. Next year, when we are on our southern tour and crossing the Shimen, the emissary will pay homage to Heng Yue with jade. Pingcheng, the capital of Fuwei, is in the north of Hengshan Mountain, but it is necessary to sacrifice to Quyang in the south. According to the orders of ancient ancestors, those who worship the same are still alive. In the autumn and August of Sui Shu's great cause, the emperor personally worshipped Heng Yue. The Book of the Tang Dynasty was written in Yuanhe, Quyang County, Dingzhou. In fifteen years, Yuezhen became more constant and had temples. ..... Since the Tang Dynasty, this has been true for historians and monuments. Therefore, it is natural to know that the sacrifice of Beiyue is in Shangquyang. The publication of Debate on Gu Beiyue is a paper on his academic philosophy. On the basis of summing up historical facts, Mr. Gu proved that Hengshan place name has a long history and a clear vision, which has existed since ancient times.
