Zhangqiu is low-lying, surrounded by depressions in the northeast and southwest, and there are many rivers flowing through it in history. Historically, the breach of the Yellow River has become the main flood here.

Historically, the lower reaches of the Yellow River entered the sea from either the northern line or the southern line, and in the triangle of the northern and southern lines, yanggu county changed its course six times. According to "Yanggu County Records", "Before the early Song Dynasty, the Yellow River flowed through the north-central part of our county, which burst every year and was flooded by Zhang. After the Song and Yuan Dynasties, the Yellow River moved south, and the water burst northward and headed for Zhangqiu. The canal dikes have been opened repeatedly, and the people are miserable. " Therefore, it has been rumored that Zhang Qiu's real name is "Rising Autumn", which means that every summer and autumn, water often rises and causes disasters. When people talk about the color change of water and are eager to subdue the flood, they have removed the three points of the word "Shang". Frequent floods are the most serious threat to Zhang Qiu's economy and the backbone of water transport. In order to protect the canal navigation, the Yellow River has been regulated many times, but the floods have not been eliminated. Finally, in 1855, the Yellow River burst in Tonghua Cave, Henan Province, and the Yellow River diverted, cutting off the north-south traffic of the canal, thus cutting off the economic lifeline of Zhang Qiu.

In A.D. 139 1 year, the traffic in the former Wukou, Mandongshan, Yu 'an Lake and Huitong Henan North Yellow River was interrupted. It was not until A.D. 14 1 1 year that Huitong River was re-navigable. After a large-scale regulation, it was navigable again and was suspended for more than 20 years. The suspension of classes has dealt a great blow to Zhang Qiu's economy. According to historical records, during the fifty years from 1437 (the second year of next year) to 1492 (the fifth year of next year), there were seven major floods in Yanggu, Shouzhang and Dong 'e counties, among which the Yellow River burst six times and Shawan burst five times. Among them, "Ming Daizong (A.D. 1452) Jingtai in May of the third year, Shawan was re-decided, the river was gradually cut off, and the water transportation was terminated. In the fourth year of Jingtai, Xu Youzhen was sent to Zhang Qiu to rule the river and Shawan ... Jingtai successfully ruled the river in six years, and the north-south water transport resumed. " It lasted for four years. "In the fifth year of Hongzhi (AD 1492), the banks of the Jinglongkou River burst, and the water in the north must be under Zhang Qiu, which washed away more than 90 feet on the east bank of the canal, and the water was taken to the southeast sea. The right deputy of Duchayuan was ordered to govern the river. The canal was dug three miles in front of the west bank of the canal, named' Moon River', which made the water flow into Huitong River in the north, so it blocked the breach on the east bank, starting from Huanglinggang in the west (now the north of Minquan County, Henan Province) and Xuzhou in the east, and damming the tributaries from the north, forcing all the water from the Yellow River to flow into the southeast sea. In order to prevent Zhang Qiu from being washed away again, a rolling stone dam was built to the south of the old crevasse. In the eighth year of Hongzhi, the river course was completed and Zhangqiu was named Anping Town. " Liu Daxia's river regulation this time is relatively thorough, which basically ensures that Zhang Qiu 100 years will not be washed away by water, and the water transportation will be unimpeded, thus laying a foundation for the long-term stability and prosperity of Zhang Qiu.

After entering the Qing Dynasty, the Yellow River became more and more unstable, and more and more accidents occurred in Zhangqiu Canal. According to incomplete statistics, from A.D. 1650 (the seventh year of Qing Shunzhi) to A.D. 1855 (the fifth year of Qing Xianfeng), there were 28 major floods in Yanggu, Dong 'e and Shouzhang counties, of which 22 were caused by the breach of the Yellow River or the flooding of the river. These floods are amazing. For example, "Shouzhang County Records" records a folk song in the twenty-third year of Daoguang: "It was a flood in the year, saying,' In the twenty-third year of Daoguang, the flood covered the sky'". Especially at this time, the Yellow River burst more and more from Zhang Qiu into the sea, which became a precursor to the great diversion of the Yellow River in Xianfeng five years. "Yanggu County Records" records: "In the seventh year of Shunzhi (AD 1650), the Yellow River was re-established, and the north flow broke the east bank of Zhangqiu, and the Daqing River entered the sea. Yang Fangxing, the main river, was ordered to block, and the Yellow River still belongs to Xuhuai Ancient Road "; "In the sixty-first year of Kangxi (A.D. 1722), the north bank of the Yellow River was reset, and the river rushed back to Zhang Qiu, breaking the East Embankment and entering the Daqing River. Ma Qi, a university student, led troops and people to control water, which ended at the end of that year"; "In the eighth year of Yongzheng, it rained in June, and the river settled at Shawankou"; In August of the tenth year of Qianlong, "He Juechong didn't hang the sword platform (Zhangqiu Town)"; Jiaqing twenty-four years, "autumn in September,? The Qing government did not come up with effective countermeasures, which eventually led to the irreversible diversion of Xianfeng for five years.

In June of the fifth year of Xianfeng, the Yellow River was decided by the copper tile compartment in Yanglan, Henan. According to "Shandong Tongzhi", after the river was decided, it was "divided into three parts, one part was placed in the south of Cao Zhou, Shandong Province by King Zhao, and the other part was placed in the north and south of Dongming, Zhili. It is near Zhou Pu, Fanxian and Zhangqiu, Shandong Province, and transported by Daqing River. The oyster mouth is covered by two rivers below Beixiao Temple in tiemenguan and enters the Bohai Sea. Below, Pu, Fan, Shouzhang and Dong 'e were flooded. "As a result, the first generation of Yellow River water in Zhangqiu flooded everywhere, and the sliding trend changed every year. It was not until the Jindi and Huang Lin levees were built one after another that the Yellow River flowed back to its present channel, and the flood of the Yellow River in Zhangqiu came to an end. The great diversion of the Yellow River not only ended its 600-year history of flowing south into the sea, but also cut off the north-south traffic of the canal, completely destroyed the economic lifeline on which Zhang Qiu relied for development, and turned this historic town with developed traffic into a closed and remote corner, where businesses either moved or closed ... The economy declined rapidly. On the eve of liberation, Zhang Qiu became quite depressed.

Zhangqiu Town, which is thriving by the river.

Zhangqiu Town prospered due to the canal, declined due to the flood of the Yellow River, and now prospered according to the Yellow River. From 65438 to 0946, the people began to control the Yellow River. Today's Yellow River has made brilliant achievements and An Lan. Zhangqiu, an ancient historical town, has also been revived with the harnessing of the Yellow River.

From the middle of last century, Yanggu began to build rainbows to attract water from the Yellow River. By the 1980s, Taochengpu Yellow River Diversion Gate was built. Zhangqiu Town is an important agricultural production base in Yanggu, mainly including wheat, cotton and corn. There is Yellow River irrigation, where the land is fertile, irrigation and drainage facilities, and grain and cotton yield every year.

The development of agriculture laid the foundation for the development of industry. Today, Zhangqiu Town Party Committee and Government adhere to Theory of Three Represents and put forward the strategy of revitalizing the town through industry in economic development. A private industrial park covering an area of 500 mu has been established, forming several leading industries such as plastic chemical industry, halal meat processing, mechanical casting and flour processing. With the help of canal culture and Jingyanggang tourism development, fully tap the profound cultural heritage of the ancient town of Canal, build a new town based on a high starting point, widen the east-west street by 30 meters, and the streets on both sides are high-rise buildings with current popular style, with a strong modern atmosphere; Nanbei Street is 25 meters wide. It is a pedestrian street, commercial street and food street with simple and elegant style. Zhangqiu Town has favorable policies, superior environment and simple folk customs, providing people with a safe, comfortable, relaxed and beautiful investment environment. Nowadays, the slaughtering and processing enterprises of meat products have developed rapidly, from single slaughtering to multi-variety slaughtering of pigs, cattle, sheep, chickens and ducks, reaching the production scale of slaughtering and processing 300,000 pigs and 6,543,800 sheep (cattle) annually, earning 6,543,800 US dollars.

Get out of the predicament and see the road clearly. Faced with the new situation and development needs, the broad masses of cadres and people in Zhangqiu Town, on the basis of emancipating their minds and renewing their concepts, set up the town with agriculture, and at the same time tap the history and culture of the Canal and the Yellow River, develop tourism, strive for greater achievements in all aspects and realize the revival of the ancient town at an early date.
