Yu Chenglong was born on August 14, 1638 (the fifth day of the seventh lunar month in the third year of Chongde in the Qing Dynasty). His birthplace was Gaizhou, Liaodong. He died in the Huai'an River Governor's Office on April 16, 1700 (the twenty-seventh day of the second lunar month in the thirty-ninth year of Kangxi's reign) at the age of sixty-three. Yu Chenglong's biological father is Yu Guoan, and his biological mother is Kang. When Jackie Chan was 11 years old, his family moved from Long to Tongzhou, Beijing, and later moved to Zhangjiawan, Tongzhou. When Jackie Chan was 13 years old, he moved to Yanqing Prefecture. When he was 16 years old, he moved to Nanfangshang Village, Gu'an and settled here. Because the children of the Eight Banners were not allowed to take the imperial examination, Yu Chenglong began to study Manchu at the age of 16, and entered the Imperial College at the age of 20 to study. After graduating at the age of 23, he was admitted to the Ministry of Civil Affairs to do writing work (ie, paperwork).

Because his uncle Yu Deshui, who had many military exploits, had no heirs, his biological father Yu Guoan was appointed to be adopted by Jackie Chan and given to Yu Deshui. In the seventh year of Kangxi, Cheng Long Yinsheng was appointed magistrate of Leting County. In the eighth year, he was appointed magistrate of Luanzhou. He repaired the Luanhe River and controlled banditry. Because of his outstanding political achievements, outstanding talents and uprightness, he moved to Tongzhou to know the state in the 18th year. Yu Chenglong served as an official in Tongzhou for three years. He established and developed free schools and selected good teachers for poor children in urban and rural areas so that they could attend school for free and receive the education they deserve. He was also good at rectifying criminal cases, strictly abiding by the rules and regulations set by the court, making fair decisions and conducting public trials, so thieves from other counties did not dare to enter Tongzhou to steal. Twenty years ago, Qingduan Yu Chenglong (Beiming), the then governor of Zhili, admired this subordinate with the same name as himself and recommended him to Shangshu. Yu Chenglong lived up to expectations and was promoted to the prefect of Jiangning (now Nanjing City) due to his outstanding political achievements. In Jiangning, Yu Chenglong devoted himself to serving the people, was honest and upright, and was quite similar to Yu Chenglong (Beiming) in Shanxi. Emperor Kangxi visited Jiangning in the south and promoted Yu Chenglong to be the envoy of Anhui. In response to the common phenomenon of Han military officials in the Eight Banners at that time "eliminating extravagance and being wanton and unrestrained", Emperor Kangxi ordered everyone to follow Yu Chenglong's example. He said: "Hereby When I patrolled the south of the Yangtze River, I met civil and military officials, soldiers and civilians, and all of them said that the governor of Jiangning, Cheng Long, was honest and caring for the people. If you are worried and want to get rid of old habits, if there are those who clean themselves and love the people like a dragon, I will promote them."

In the 23rd year of Kangxi (1684), Yu Chenglong was ordered to regulate the river for the first time. With the title of Anhui Inspector General, he "supervised Xiahe" and proposed the idea of ??"dredging the mouth of the sea and constructing the waterway of Xiahe". There was a conflict with the idea of ??Jin Fu, the governor of the river, to "build a long dike on the lower river and divert water into the sea". At that time, Jin Fu believed that the Huaihuang embankments should be overhauled by the method of "confining water to attack sand" so that "the river could return to its original course." Facts have proved that Jin Fu's river management strategy is indeed effective, but Yu Chenglong's river management ideas also have a certain scientific nature. After Jin Fu's death, Yu Chenglong was appointed as the governor of the river. He fully absorbed Jin Fu's river management strategy and formed a new river management concept of "building embankments" and "dredging" simultaneously, which reflected his spirit of seeking truth from facts and also served as a guide for him. Later, the theoretical foundation was laid for the management of Yongding River.

In the twenty-fifth year of Kangxi (1686), he was specially awarded the title of Governor of Zhili. Zhili is located in the Gyeonggi region, where the royal family, relatives and landlords rely on their power to run rampant in the countryside. Yu Chenglong was upright and unafraid of power. He severely punished the lawbreakers who bullied others, which dealt a blow to the arrogance of local powerful forces in the Gyeonggi area. Emperor Kangxi greatly appreciated this and told the academicians: "Looking at all the officials today, although there are some who are clean in character, they are afraid of the law of the country. There are very few people who are truly honest and upright like Cheng Long, the governor of Zhili.

In the twenty-sixth year, he was awarded the title of "Prince Shaobao" for his incorruptibility. Fortunately, he was in charge of the state and was given a thousand pieces of gold and a yellow saddle and bridle. In the winter, he secretly reported to Emperor Kangxi: "The official has been imprisoned." Ming Zhu and Yu Guozhu are sold out. Emperor Kangxi asked Gao Shiqi: "Why is no one participating in the impeachment?" Gao Shiqi replied: "Who is not afraid of death?" "In the twenty-seventh year of Kangxi (1688), the censor Guo Xiu impeached Nalan Mingzhu for forming cliques for personal gain and excluding dissidents. Emperor Kangxi immediately deposed Nalan Mingzhu, the bachelor, and handed it over to the bodyguards to retain him as appropriate.

Twenty In the ninth year, he moved to Zuodu to be the censor and the commander of the Han army.

In the 31st year, Wang Xin ordered him to be reinstated as the governor of the river. He was appointed as the assistant leader. The money was used to buy the willow bundle, but the Ministry of Works refused to reduce it. Jackie Chan was not in vain to help build the Gaojia Weir and the heavy embankment, and raised money for his husband to live in a distant place. The work was stopped and the new title was cancelled. Please ask for exemption.

In the 33rd year, he summoned the capital and stated that the canal from Tongzhou to Yixian and the Yellow River from Xingze to Dangshan should be built thicker and thicker if they are low and thin. In the 34th year of Kangxi's reign (1695), the masonry work at Gaojiayan was improved, the river was diverted at Maochengpu, and embankments at Qingjiangpu, Jiangdu and Gaoyou were carried out.

In the 34th year of Kangxi's reign (1695), When the Qing army sent troops to the northwest, Emperor Kangxi personally conquered Galdan, and ordered Yu Chenglong to coordinate and supervise the transportation of food and wages with the title of Zudu Yushi. After Yu Chenglong overcame difficulties and obstacles and ensured the supply of food and wages for the conquering army, he was awarded the title. He was worshiped as Labulhafan, hereditary.

On February 27, the thirty-seventh year of Kangxi's reign (1698), Emperor Kangxi ordered Cheng Long to serve as the governor of Zhili, the Minister of War, and the censor of Youdu. He was also in charge of the governor of Zhili. At this time, the Hun River flooded and merged with the river in the south of Yongding Prefecture. When he was in danger, he was ordered to go with the Westerner Anduo (Portuguese missionary) to investigate and make a feasible plan to control the river. After six months of treatment, Yu Chenglong proposed to change the Hun River to Yongding River, and got the approval. Kangxi agreed and named it Yongding River.

On November 27 of that year, Yu Chenglong was ordered to serve as Minister of War and Governor of the River to govern Huanghuai. At that time, in the Huaiyang area, the Huanghuai River was swollen and many places were flooded. Yu Chenglong traveled across the two rivers to survey the disaster situation, and applied the effective methods and experience of regulating the Yongding River to the management of the Yellow and Huaihe Rivers. However, due to the complicated river affairs, he eventually became ill from overwork. In the thirty-eighth year of Kangxi's reign, Emperor Kangxi once again visited the south of the river. Seeing Yu Chenglong's frail health, he gave him medicine, imperial poems, etc. He performed his duties diligently, but his illness worsened, and he still managed the river despite his illness. In October, he asked for a two-month break, and Emperor Kangxi ordered the imperial doctor to treat him. In February of the following year, Yu Chenglong went to Huaihe for inspection while ill, and his condition worsened. On the 23rd, he called his son Yongyu to the sick bed and told him: I am extremely ill and cannot be cured without medicine. The two rivers are very important, and it is difficult to manage them even if I am ill. I urgently need to send more capable ministers, so as not to interfere with state affairs and aggravate my sins. Until his death, he never forgot to govern Huanghuai. Four days later, Yu Chenglong died of illness in Huaishu. Kangxi mourned deeply after hearing the news, sent people to offer sacrifices, and gave him the posthumous title of Xiangqin.
