In 565, Emperor Wucheng, believing in astrological signs that the imperial reign would be changed, passed the throne to Gao Wei. He took the title of "Taishang Huang" (retired emperor), while creating Empress Hu the title of "Taishang Huanghou" ("retired empress"). However, the matters of state were still decided by him, rather than the nine-year-old Gao Wei. During this period, Gao Yan was initially created the Prince of Dongping and then the Prince of Langye. Because of the retired emperor's and empress' great favor toward Gao Yan, he became exceedingly honored, and at times he would question his parents as to why his brother, who was weaker in personality than he was, was emperor. Emperor Wucheng and Empress Hu at times considered deposing Gao Wei and making Gao Yan emperor, but ultimately did not do so.
