In 1720, Longkodo was named the minister in charge of Lifan Yuan by the ailing Kangxi Emperor, overseeing affairs of ethnic-minority border regions.
The biggest mystery surrounding Longkodo is the exclusive attention the Kangxi Emperor gave him before his death.
His military support ensured a non-violent transfer of power between the Kangxi and Yongzheng emperors.
After the Yongzheng Emperor ascended the throne, Longkodo was given a position on the four-person imperial council, and was the President (Shangshu) of the Board of Governance.
Longkodo was later disgraced, charged with a list of 41 crimes, and then forced into house arrest by the Yongzheng Emperor at Changchunyuan.
