理藩院
A few weeks after the death of the Kangxi Emperor, the Yongzheng Emperor enfeoffed Yunsi as "Prince Lian of the First Rank" (; Manchu: "hošoi hanja cin wang") and he sat on the emperor's top advisory board along with Yinxiang, Maci, and Longkodo. Yinsi was charged with overseeing the "Lifan Yuan", the bureaucratic organ in charge of the affairs of the Qing dynasty suzerain lands such as Mongolia. Despite bestowing Yunsi with the highest honors, the Yongzheng Emperor targeted those court officials who were Yunsi allies. The Yongzheng Emperor frequently criticised Yunsi for not performing his duties properly. In 1724, for example, the emperor ordered Yunsi to kneel in the inner reaches of the Forbidden City for an entire night, ostensibly for an infraction committed during his oversight of the "Lifan Yuan". In early 1725, the emperor forcibly exiled Yunsi's wife to the interior, and forbid all communication between the two. By 1725, Yunsi had completely lost favour with the emperor, and became the target of trumped-up charges and accusations that eventually led to the stripping of Yunsi's princely title, along with his banishment from the imperial clan.
