First, the Qing Emperor sent Fan Xian to Northern Qi to complete a dangerous mission, which was to escort Xiao En and exchange him for Yan Bingyun. The Qing Emperor had special attention and protection for Fan Xian. He hoped that he could return alive. Secondly, Fan Xian's performance and actions in Northern Qi also played a key role. In Northern Qi, he worked with the Northern Qi Emperor, Zhan Doudou, and the Brocade Guard, Shen Zhong, to reopen the smuggling channel for products produced by the Qing Kingdom's palace treasury in Jiangnan to Northern Qi. Fan Xian had also used his relationship with Haitang Duoduo to meet with the Northern Qi Emperor in private and persuade the empress dowager. He had even publicly stated that the Emperor and the empress dowager were not on good terms and urged the two sides to oppose each other.
