Hai 'an County is the earliest land in Nantong, where the Neolithic culture of Qingdun was bred 5000 years ago. After the Spring and Autumn Period, Hai 'an began to enter the written records, and the records about Fengshan can be found in the Records of Ancient Hailing: "There is an earthen mountain in the northeast half of Hai 'an, named Yushan Mountain, also known as Phoenix Mountain, which is three feet high and hundreds of steps a week. There is a stream in front of the mountain and a stone bridge at the end of the stream road. "There is a legend circulating among the people of Fengshan Hai 'an in the north of Hai 'an Town, which tells another cause of Fengshan: a long time ago, there was a serious drought in Hai 'an area, and drinking water became a problem for villagers. No way, everyone had to dig wells to get water. In Qiuhu Lake, northwest of Hai 'an, 749 wells were dug continuously, but no water was found. When digging the fiftieth well, only three feet were dug, and a golden light rose to the sky. It turned out to be a blooming white jade box. Suddenly, the stone box opened automatically and a pair of golden phoenix flew out. Everyone was surprised when a spring water flowed out of Bai Yushi's box and reached the ground in the blink of an eye. Golden phoenix flew to the west, south and north of the village. Wherever he flies, there is spring water flowing. With the farmers' drinking water, the fields are well sown, and the villagers are scrambling to sow. The crops are growing well and everyone is happy. Thanks to this pair of golden phoenix. There is a local villain named Chen, who owns a thousand hectares of land and hundreds of houses. In the past few days, golden phoenix has been watering the farmland with spring water, but he just won't fly to his field. Pockmarked Chen San was very angry. He ordered his evil slave to hunt the phoenix all over the ground with a net tied with bamboo poles. Golden phoenix only cared about water diversion and irrigation, but before he could escape, orpiment was unfortunately arrested; Seeing that the momentum was not good, Xiong Feng quickly flew south. Asako Chen San personally carried the caught burns into the house. Unexpectedly, when Huang struggled, the golden retriever fell to the ground and turned into a flame, which quickly burned up Chen San's hundreds of rooms. Huang and Chen San mutually assured destruction in the fire. With gratitude, the villagers built a grave for the dead Huangcuo soil and piled it into a big mound, named Phoenix Pier, in today's Qiuhu Town, Hai 'an. The phoenix flying south flew to the northern suburb of Hai 'an and fell down, dying of anxiety. The local villagers also built a grave for it, namely Fengshan. According to legend, Fengshan is a tomb left by predecessors to bury sacred objects. Some tombs in history, such as Xixia tomb, were built by man-made piles of soil. Can Fengshan also be someone's grave? The only relevant historical materials that can be found are: In 646, in the twentieth year of Zhenguan in the Tang Dynasty, General Wei Chibaolin, the son of Weichi Gong, built Guangfu Temple in Hai 'an. Haian-Ma Pingchuan, there is no danger to defend. As a general, will he build a garrison of heaped-up mountains? During the Tang and Five Dynasties, there were frequent wars, and Zhu Wen's army built operational bases here. By the Song Dynasty, the heaped-up mountains had partially collapsed. Yue Jiajun built heaped-up mountains just to add Gao Fengshan to the original foundation? And the folklore Fengshan is a mausoleum, because it was once an ancient battlefield, spilling the blood of soldiers and burying their bones? "Castle Peak has the honor of burying loyal bones. Why do you die without regret?" It is not uncommon for people to miss those who died for their country. It is also possible that a strong man died in Fengshan and eventually evolved into a legend of the Phoenix.
