Yongzheng Emperor
When the Yongzheng Emperor became seriously ill, Yunli was tasked with supporting the heir to the throne, Hongli. The Yongzheng Emperor died in 1735 and was succeeded by Hongli, who became historically known as the Qianlong Emperor. During the Qianlong Emperor's reign, Yunli was empowered with more authority and given more duties with commensurate recognition.
