During the period of 1963, the sudden severe drought caused the water level of Hongze Lake to drop sharply, and a large number of scattered stone statues surfaced. As a result, experts found that these stone statues are all images of Kirin, lion and civil servants and military commanders, which are exclusive to the royal family. According to expert research, this is the tomb of Zhu Yuanzhang's ancestors recorded in historical books, located in Xuyi County, Jiangsu Province. This forest tomb buried Zhu Yuanzhang's grandfather, great-grandfather, great-grandfather and their wives. The ancients paid special attention to geomantic omen when building tombs, and cemeteries generally paid great attention to mountains and rivers, especially royal tombs. The choice of tombs should generally conform to the three wonders of mountains, water and cases, and it is best to have a terrain surrounded by mountains.
Zhu Yuanzhang's ancestral grave is in a swamp in Wang Yang, completely out of touch with the land of Feng Shui. Zhu Yuanzhang himself knew that this place was not a treasure trove of geomantic omen, but as an emperor, why didn't he move his ancestral grave? Because he really can't move, if the ancestral grave moves, the kingly way inside will be revealed, and he is worried that Daming Jiangshan will be lost. However, Zhu Yuanzhang did not ignore it, but rebuilt his ancestral grave on a large scale, filled all the original low-lying places, made stones for him where there were no mountains, and made artificial rivers for him where there was water shortage, creating the most ideal place for geomantic omen. Since Zhu Yuanzhang's ancestral graves have been transformed into feng shui treasures, why can't he escape the bad luck of being flooded for 300 years?
During the Hongzhi period, the north branch of the Yellow River was cut off in the water conservancy project presided over by Liu Daxia at that time, which led to a large influx of Yellow River water into its south branch and into the Huaihe River. People along the Huaihe River suffered greatly, and they were attacked by floods. In order to solve this problem, Pan Jixun, a famous water control expert in Ming Dynasty, put forward the strategy of storing the Huaihe River and brushing the Yellow River. However, practice has proved that his method doesn't work, and no matter how the Huaihe River water is collected, it still can't stop the surging backward flow of the Yellow River. A large amount of sediment from the Yellow River also began to accumulate at the mouth of the Huaihe River, which led to the rising of the Huaihe River bed and eventually flooded Ming Taizu, the ancestral grave of Zhu Yuanzhang.
