In A.D. 1725, his second son, Yuzhu, made a big mistake because of his bad conduct. Yongzheng dismissed him and handed over Yuzhu to Longkeduo for discipline.
In the fourth year of Yongzheng, that is, A.D. 1726, one of Longkodo's men paid bribes in the name of Longkodo. After this incident was discovered, many things about Long Keduo were also revealed. Longkodo accepted bribes from Nian Gengyao, Governor Zhao Shixian and Bowman, and Governor Gan Guobi and Yuji were also known by Yong Zhengdi. So Yong Zhengdi ordered the killing of this man, and also removed Longkodo from his office. Shortly after this incident, Yong Zhengdi sent Roncado to the border to discuss some state affairs with Russia.
At first, after discovering that A Ling and others colluded with Nian Gengyao for personal gain, and after Nian Gengyao stepped down, Yong Zhengdi asked Langkodo if he was involved. Longkaoduo was afraid to tell the truth, so he lied and fooled him. Since then, Yong Zhengdi has planted the seeds of doubt on Rondo.
In A.D. 1727, Longkodo was negotiating the border issue with Russia. At this time, Longke's evidence of cronyism and possession of jade was discovered by Yong Zhengdi. Yong Zhengdi was furious and immediately sent Longkeduo back to Beijing, and copied Longkeduo's home. Also in this year's 10 month, Yong Zhengdi sentenced Long Keduo to 4 1 felony and imprisoned Long Keduo in Changchun Garden. In A.D. 1728, Roncodo died.
