In the eighteenth year of Shunzhi (A.D. 166 1), Yu Chenglong became an official by participating in scientific research. His first stop was the magistrate of a county under the jurisdiction of Liuzhou Prefecture in Luocheng, Guangxi, where the Qing Dynasty was extremely vicious and bandits were rampant, and he began his official career here for 23 years. When he first arrived, the local social order was extremely chaotic and lawless. Class contradictions and ethnic contradictions are very acute, and ordinary people are fidgeting and complaining a lot.
In the face of the confusion of the two predecessors, Yu Chenglong calmly responded. With superb wisdom and strong will, he adopted the strategy of combining appeal with military repression, resolved all kinds of sharp contradictions and quickly opened up the situation. When he was in office, he set an example, be upright and upright, remain uncorrupted, love the people as a son, handle affairs fairly, and reward and punishment clearly. Under his rule, the social atmosphere gradually improved, and Luocheng became a small town in southern Xinjiang with simple folk customs, beautiful environment, prosperous economy and people living and working in peace. In the 12th year of Kangxi, Yu Chenglong was promoted to be the magistrate of Wuchang, taking full charge of military affairs in Wuchang. During his tenure, he persuaded Liu of forty-eight villages to surrender to the court and put down the bandit rebellion. Since then, it has been recommended by Taizikang as Fujian provincial judge. In Fujian, Yu Chenglong met his long-lost friend Zhang Jiren.
Yu Chenglong thinks that the case of Tong Hai in Don Juan Village has grievances, but it was blocked in the review and had a dispute with Zhang Jiren. Finally, he found out the case, and his good friend Zhang Jiren was demoted, while Yu Chenglong was promoted to Minister of State. He loves people as much as his son. When he sees people who work hard all day, he has mixed feelings. He wrote to Prince Kang, urging him to withdraw the order of recruiting 30,000 witches. After Kangxi heard his story, he was promoted to Zhili. During the reign of Emperor Kangxi, in case of drought and natural disasters, Yu Chenglong opened a warehouse to release grain privately, and was regarded as a confidant by Emperor Kangxi, who appointed him as the Governor of Liangjiang. When he took office in Liangjiang, he killed Hurley, the scourge of Liangjiang, and solved the problem of fire consumption in Liangjiang. He died of old age and overwork. In the early years, after Kangxi learned of his death, he praised Yu Chenglong in the temple and praised him as? Honest and upright officials are the first in the world? .
