Yang Xuangan
Yang Xuangan, however, believing that he needed to capture Luoyang to show that his rebellion was serious, commented that Li's "low strategy" was in fact "high strategy," and headed toward Luoyang. However, as Li had predicted, Tang had warned Emperor Yang's grandson Yang Tong the Prince of Yue and the official Fan Zigai (樊子蓋), whom Emperor Yang left in charge of Luoyang, and Luoyang's defenses had been prepared. While Yang Xuangan and his brothers gained some victories, he could not quickly capture Luoyang. Meanwhile, many young noblemen were joining his cause. After he captured the highly regarded official Wei Fusi (韋福嗣), he trusted Wei as well and did not only trust Li any further, but strategies that Wei submitted were not wholeheartedly in support of the rebellion. Li requested that Yang Xuangan kill Wei, but Yang Xuangan refused. Li made the comment to his relatives, "The Duke of Chu wanted to rebel, but does not know how to gain final victory. We are now like turtles stuck in urns."
