In the fifth year of Yongzheng, that is, A.D. 1727, Longkodo was sent by Yong Zhengdi to negotiate with Russia on the border issue between the two countries. The negotiation was about to succeed, but it was discovered that Longkodo colluded with others for personal gain and even hid jade articles. After Yong Zhengdi got the evidence of Long Keduo's crime, he immediately sent someone to arrest Long Keduo and gave him the property of Long Keduo.
In the same year 10, Yong Zhengdi sentenced Long Keduo to 4 1 felony and imprisoned Long Keduo in Changchun Garden. Long Keduo's eldest son was dismissed and his second son was sent to Heilongjiang. 1July 28, Long Keduo died in Changchun Garden.
In A.D. 1725, Nian Gengyao wrote a letter to Yong Zhengdi, but his handwriting was scrawled, and he mistakenly wrote the word "doing things at night" as "doing things at night". Yong Zhengdi took advantage of this incident, replacing officials in Sichuan and Shaanxi, removing Nian Gengyao from his post as governor of Sichuan and Shaanxi, and demanding that Nian Gengyao hand over the seal of General Fuyuan. In September of the same year, Yong Zhengdi ordered the arrest of Nian Gengyao. In December, Yong Zhengdi listed 92 counts in Nian Gengyao. In AD 65438+ 10/3, in AD 726, the Nian Gengyao family bid farewell to the historical stage with the ending of family destruction.
