Legend has it that more than 1,400 years ago, the Liang and Wei states of the Northern and Southern Dynasties competed for Shouyang (present-day Shou County), and the wei state was slightly stronger in the battle, and preemptively occupied the city of Shouyang. This Shouyang is the throat between Huainan and Jingzhou and Xiangyang, the city around the city is more than three zhang high, the moat outside the wall is also three zhang wide, more than one zhang deep, easy to defend and difficult to do, Liang Guo's soldiers and horses besieged the city repeatedly, each siege of the city killed and injured countless. Emperor Xiao Yan of Liangwu frowned all day about this.
At this time, Chen Wu, a descendant of the State of Wei, proposed to Xiao Yan to choose a narrow section on the huai river, build a dam on the river, use water as a soldier, flood Shouyang, and present a detailed map. The dam construction site is shown from Fushan (present-day Fushan, Mingguang City) in Xuyi County, Fengyang Province in the south to Sihong Mountain in the north. Xiao Yan took Chen Wu's advice. A total length of 9 miles, the lower width of more than 140 zhang, the upper width of 50 zhang, the height of 200,000 zhang, has invested more than 200,000 people, lasted 18 months of barrage damming project on October 10, 514 earth-shattering began. This is the famous "Fushan Weir" in ancient and modern times.
At first, Emperor Wu of Liang sent two generals, Zu Heng and Chen Chengbo, a water official, to arrange for implementation. Through on-the-spot inspections, Zu and Chen both believed that although the Huai River was narrow here, the Huai River was drifting and raging, the sand along the coast was loose, and it was difficult to build a weir, and it was a move to work hard and hurt the people's wealth, and they were united for an indefinite period of time, and they urged Xiao Yan to abandon the damming plan. Emperor Xiao Yan of Liangwu was furious when he heard this: "Dripping water can become a mound, shovel soil can become a mountain, since ancient times there have been soldiers to block, water to the earth weir, there is no reason why a dam cannot be built, it is clear that the two have different intentions." Xiao Yan, in order to show his determination to build the dam, did not allow anyone to raise any objections, even if he ordered the left and right guards to tie up Zu and Chen and behead them for public display. After killing Zu and Chen Er, no one dared to raise objections anymore. Xiao Yan also sent his generals to recruit civilian husbands from the front line of Xuzhou and Yangzhou, drawing 5 people from every 20 households, recruiting more than 150,000 people, plus more than 50,000 soldiers to more than 200,000 people. The people, whether it was the heat or cold, kept digging earthen dams day and night. As the dam closed, the river became more and more ferocious. As soon as the men fell from the mud, they were swept out by the raging river for dozens of feet, and they could not close it for a while. At that time, some people offered to make a pot made of iron, which was filled with soil and sunk into the water to block the river water. Therefore, Xiao Yan sent people to mobilize more than 100,000 catties of pig iron and cast it into an iron pot to sink into the water, but the result was still to no avail. Xiao Yan was so anxious that he could not close his eyes when he slept, could not eat his taste, was restless, and often took on the supervision of the work himself, and if he was slightly unpleasant, he was beheaded and thrown into the river. In addition, the weather is cold and frozen, and the people are tired all day long, and the people freeze to death, starve to death, and die of illness. At this time, there were two craftsmen, a pair of twin brothers, the brother was called Da Liu Xiang, and the brother was called Xiao Liu Xiang, and it was not a matter to see if this continued. In order to protect the other people, he took the initiative to propose to Xiao Yan to jump into the closing place, nail it into a "well" shaped wooden stake, and quickly fill in the earth and stone, so that the dam could be closed. Xiao Yan sent people to cut down trees, open mountains and quarry stones, everything was ready, and the Liu twin brothers jumped into the fierce river with their arms around them. Just listening to the loud sound of "bang", the water of the Huai River, which was as fierce as a dragon, turned its head and rushed back. A large number of civilians and soldiers on the shore took advantage of the gap to fill in the stump stones and soil bags prepared in advance to the mouth of the dam, and soon the dam closed. The time was exactly 10 April of the 15th year of Liang Tianjian (516 AD), which lasted for a full 18 months. In order to commemorate the twin brothers of Da Liu Xiang and Xiao Liu Xiang, many willow trees were planted along the dam, and a town along the river in Sihong was called Da Liu Xiang, and a village town along the river to the east of Fushan Mountain was called Xiao Liu Xiang. Later, shouting and shouting was called Big Willow Lane and Little Willow Lane.
After the construction of the Fushan Weir, the middle and upper reaches of the river were hundreds of miles along huai. Shouyang City was flooded, but only an empty city was flooded. As early as the construction of the dam by the dyeing army, the Wei army garrison general Li Chong gradually evacuated the residents of the city to the mountain. A pontoon bridge was also built on the gorge stone mountain to facilitate people's transportation. At the same time, changcheng was built on Bagong Mountain to prevent Liang Guo from attacking.
When Xiao Yan heard that Shouyang had been flooded, he was very happy. However, only an empty city was flooded, and the Wei army did not suffer much loss, while the Liang army killed and wounded nearly 100,000 civilians and soldiers, and the labor division mobilized the masses to use 2.5 million taels of silver, and no one dared to report these situations.
Xuzhou thorn Shi Zhang leopard was sent to protect the weir, Zhang Leopard was originally dissatisfied with the construction of the weir, sent him to suppress the Fushan Weir, the people are not exhausted, coupled with the flood season of the Huai River, the water level soared, in September of that year, the weir collapsed, the water breaking the embankment was like a beast, the peak of the flood was pushed forward, its sound was like thunder, hundreds of miles away can be heard, along the Huai village was washed away, the farmland was submerged, nearly 100,000 people were swept away by the flood, and the disaster was huge.
