602, Yang Guang, believing that Yang Xiu would eventually create trouble for him, had Yang Su collect evidence of Yang Xiu's wastefulness and use of items that were only appropriate for emperors. Yang Su submitted the evidence to Emperor Wen, and Emperor Wen, in anger, recalled Yang Xiu to the capital. After Yang Xiu arrived at the capital, Yang Guang further manufactured evidence that Yang Xiu had cursed Emperor Wen and Yang Liang. In anger, Emperor Wen reduced Yang Xiu to commoner rank and put him under house arrest. In 603, Ashina Dianjue, faced with rebellions from the Tiele and Pugu () tribes, surrendered to Ashina Rangan. By now, Ashina Rangan became the undisputed khan of the Göktürks. In spring 604, Emperor Wen, as per his custom, went to Renshou Palace to avoid the heat, despite warnings from the sorcerer Zhangchou Taiyi () that if he went, he would never return. While there, he grew ill, and in fall 604, he died. He was buried at the Yangling District's Tailing () tumulus mausoleum, with Empress Dugu (though not in the same burial chamber). How Emperor Wen died, however, is a matter of historical controversy. Most traditional historians relay and believe an account in which, while Emperor Wen was ill, Yang Guang tried to rape Consort Chen. When she reported the attempted rape to Emperor Wen, he became angry and had the officials Liu Shu (柳述, the husband of his daughter Yang Awu () the Princess Lanling) and Yuan Yan () the Duke of Longgu summon Yang Yong, intending to restore him. When Yang Guang found out, he, in association with Yang Su, had Liu and Yuan arrested, and then sent his associate Zhang Heng () to kill Emperor Wen, and Zhang did so. Soon thereafter, he forced Consorts Chen and Cai to become his concubines and had Yang Yong put to death, and only then announced Emperor Wen's death and took the throne (as Emperor Yang). The historian Sima Guang, in his Zizhi Tongjian, borrowing parts of analyses from the Book of Sui and the History of the Northern Dynasties, opined: Emperor Wen also established seven orchestras comprising musicians from across Asia at his court; these orchestras were expanded to nine by his son Emperor Yang of Sui.
