During the Ming and Qing dynasties, Huaiyuan Xuegong, also known as county school and official school, is located in Yanan Lixu, Huaiyuan Old County, which is the highest school for local government offices to cultivate talents, and is adjacent to the Confucius Temple that worships saints and sages.
In the old days, the architecture of the Xuegong Palace paid special attention to the feng shui of the earth. Huaiyuan County Xuegong, far away from tushan reflection, near the Jingshan mountain, "gold, wood, water, fire and earth" five elements, only the lack of "jade belt around" of the blue water. "Goldfish and jade with luoshi buckle, soap cover Zhu Banner column five marquises". The jade belt carved from beautiful jade is a symbol of the rank status of ancient officials. The purple qi of the Xuegong palace comes from the east, the sound of books is langlang, and the jade belt is surrounded, showing that the spirit of the distant land is brilliant, and the talent of the imperial examination is abundant.
In the spring of the fourth year of longqing in the Ming Dynasty (1570), Wang Zhizuo of Zhixian County, who respected Confucianism and emphasized confucianism, took office and talked with huaiyuan gentry celebrities about the feng shui landform of the palace, and deeply felt the regret of lack of water in the five elements. So he raised funds, recruited craftsmen, and dug up the soil along the walls of the Xuegong Palace, and opened a small river that was two or three meters wide, naming the Jade Belt River. Lead the Jingshan Bixi Stream, spray pearls and waves, flow into the Jade Belt River, twist and turn to the east, pass through the Xiahong Ferry, and merge into the Tao tao Huai River. Along the Yudai River, flowers and fruit trees are planted. Yangchun, peach and plum fragrance, warbling song and swallow dance; golden autumn, durian fruit full of branches, dangui fragrance. The ancients praised: "Ququ Xilai is a paitong, looking at the jade belt in the bixi from afar." The water ring resembles the Penglai Realm, and the clouds and mist are faintly langnan wind. "Unfortunately, over time, the Yudai River was annihilated by flash floods, and the ruins were closed to the south of the city.
Yunlonggang, formerly known as Huangnigang, is located under the Baopu Rock in Jingshan Mountain, which the ancients believed to be the base of Huaiyuan Xuegong. In the seventh year of Ming Zhengde (1512), the inspector Huang Rujin was ordered to inspect huaiyuan county school, climbed the Huangnigang behind the xue palace, saw that the xue palace was backed by Jingshan Mountain, facing Changhuai, the beauty of the mountains and rivers, the dragon vein gathered at the end, breathtaking: "On both sides of the Huai River, where can you find such a clean and beautiful place to be a xue palace?" Huaiyuan County will be full of talents and humanities! The inspector praised, Huang Nigang was full of light and his value doubled. During the Ming Dynasty, some residents of the county town tried to make it easier for themselves to dig up earth to build houses in Huangnigang, which accumulated over time and damaged the vein of the Xuegong. This incident alarmed Yang Bao and Sun Bingyang, who were from Jinshi and had served as a military attendant, and Who had served as deputy envoys to Guangdong. In the twenty-sixth year of the Ming Dynasty (1598), Yang Baoyuan and Sun Bingyang came forward and proposed to rename Huangnigang to Yunlonggang and vigorously carry out training.
During the Ming Dynasty, the "Pei Supplement Yunlonggang Record" records that Yunlonggang is a loess hill outside the gate of Huaiyuan Fengchi, and the remnants of Jingshan Mountain stretch to the loess gang, just like the meandering Wolong waiting to fly, becoming the source of the feng shui vein of the Xuegong. Climbing to the Huangnigang overlook, Tu Mountain towering green, Huai Shui dragging blue, Qinglong Bixi two waters, surrounded by left and right, gathered in front of the Xuegong, and then rushed into Huai, it is really a rare dragon vein treasure land. In order to prevent people from taking soil in Huangnigang, it affected the feng shui of Huaiyuan Xuegong. Yang Baoyan, Sun Bingyang, and other officials and scholars discussed and suggested that Huangnigang be renamed Yunlonggang, and that the two levels of Yamen in Fengyang Province and Huaiyuan County should post a notice prohibiting digging pits and taking soil in Yunlonggang. Next, everyone donated money to buy soil and stones to cultivate and protect Yunlonggang.
During the Kangxi Dynasty of the Qing Dynasty, Qian Jian of Huaiyuan County inspected the terrain of the Xuegong Palace and took the initiative to donate his own Qilu to cultivate Yunlonggang again. During the Qianlong period of the Qing Dynasty, the eastern slope of Yunlonggang was dug into a large pit of Zhangyu, and Huaiyuan was not talented, and few people in the middle were recruited. Hanlin Taishi Sun Su and the well-known talent Yang Shiwei, remembering the hometown of Yunlonggang, the earthly pulse is related to the cultural movement of the Keju, and together with the local people who are happy to do good deeds and are eager to be righteous and righteous, they not only make up for the rich and handsome Cultivation of Yunlonggang, but also built a hexagonal pavilion with exquisite clarity and flying eaves on the post, naming the Lingxiao Pavilion. Ling XiaoTing, which means the title of the golden list of hard reading scriptures, Huaiyuan students are walking in the clouds. During the Qing Jiaqing period, the Ling Xiao Pavilion was destroyed, and there were people who stole the loess in yunlonggangdong. The Xuegong mobilized people to plant pomegranates and other fruit trees in Yunlonggang, and paid the caretakers with the income of the fruit trees, and the slope was closed with blocks and stones, so that the soil collectors could take advantage of it.
After the birth of New China, Shanghai Southeast Medical College (now Anhui Medical University), Anhui Water Conservancy School (now Anhui Water Conservancy Technical College), huaiyuan no. 1 Middle School successively ran schools here, Yunlonggang became a campus, and gradually forgotten by people.
