Wendi
In summer 604, Emperor Wen, while visiting his vacation palace Renshou Palace (仁壽宮, in modern Baoji, Shaanxi), grew gravely ill. Traditional historians allege (but admit that they did not have conclusive proof) that while Emperor Wen was growing ill, Yang Guang tried to rape Consort Chen. When Consort Chen revealed this to Emperor Wen, Emperor Wen became angry and wanted to depose Yang Guang and restore Yang Yong. However, Yang Guang and Yang Su had the two officials that Emperor Wen entrusted this task to—Liu Shu (柳述, the husband to Yang Yong's sister Yang Awu () the Princess Lanling) and Yuan Yan () -- arrested, and Emperor Wen soon died, a death that most historians attribute to assassination by Yang Guang's associate Zhang Heng ().
