Tuhai river test

So, when did the Heliu River turn into a river? According to textual research, it was the Shang River dug in the Han Dynasty and the Tuhe River that appeared later that evolved into today's Tuhai River. According to historical records, after the Yellow River burst in the fourth year of Han Hongjia (BC 17), "Guanxian County was twenty-one, and Guanting House was forty thousand defeated" (Hanshu Gouzhi). In order to vent the flood of the Yellow River, Xu Shang, a captain of the riverbank, dug a commercial river that started from today's Gaotang and passed through Yucheng, Linyi and Shanghe. Since then, there has been another earth river between the Yellow River and the Shanghe River. Because the Shanghe River and Tuhai River played a great role in flood control and drainage, they continued until the Ming Dynasty. In the mid-Ming Dynasty, the Shanghe River merged with the Tuhe River in the south of Huimin, forming the modern Tuhai River. At the beginning of the formation of Tuhai River, the name was quite confusing. Ming Jiajing's "Wuding County Records" said: "Fifty miles south of the city, now called Tuhe, the old records called Tu Hai Old Road", "Huimin ditch looks south at the Haihe River". Until the Qing Dynasty, some local chronicles still called Tuhai River "the river of soil injury (business)".

In the Qing Dynasty, Tu Hai Hedong turned to Huajia Village in Zhanhua, and passed through Kongjia, Xiahe and Laomuzui, also known as Weihe River. At that time, the Tu Hai River was flooded and washed away by the tide. Cargo ships from the south, northeast and North Korea could reach Sanhe Lake smoothly, and some even reached Huimin along the Matusha River. After the Yellow River burst three times in Guangxu and the Republic of China, the Weihe River silted up to the ground, forcing the Tuhai River to enter the Taoer River from Guofuxi in Zhanhua to the north. According to statistics, from the formation to the establishment of People's Republic of China (PRC), Tuhai River burst 2 1 time and was treated 23 times. With the deepening of water conservancy reform, history has given Tuhaihe a new mission. Located on the Tu Hai River at the intersection of Tuhai River, Matu Shahe River and Fujia River, a scenic spot integrating vacation, leisure and tourism has begun to take shape. So it is named Sanhe Lake, where the river is 263 meters wide and the waters in the scenic area (from Liuzhenqiao to Shijiacun) are more than 2,500 mu. If you go boating in the misty Sanhe Lake and look at the majestic sluice and the green tree promenade on both sides, it is said that it is a fairyland on earth, and the deep and quiet feeling makes people feel relaxed and happy.
