Emperor Wen died in 604—a death that traditional historians generally believe was a murder ordered by Yang Guang, although they admit a lack of direct evidence—and Yang Guang took the throne as Emperor Yang. In 605, he created Crown Princess Xiao empress. He soon turned away from the virtuous living style he engaged in to please his parents, and he lived luxuriously, with tens of thousands of women filling his palaces. He still maintained respect for Empress Xiao, and he made many of her relatives, including her older brother Xiao Cong the Duke of Liang (Western Liang's final emperor) officials in his government. However, Yang Zhao, who became crown prince, died in 606, and Yang Jian lost Emperor Yang's favor in 608 over his use of witchcraft against Yang Zhao's sons. Empress Xiao often accompanied Emperor Yang on his tours around the empire, and she saw that he had lost his virtues. She wrote a circumspect poem to try to get Emperor Yang to change his ways, but he either did not realize that was her intent, or simply ignored the poem.
