Yang Xuangan
In summer 613, Emperor Yang crossed the Liao River again and put Manchuria under siege. However, at this time, news arrived that Yang Su's son Yang Xuangan had rebelled near Luoyang. With the people disaffected by the Goguryeo campaigns, Yang Xuangan received much popular support and threatened Luoyang. Emperor Yang, in fear, lifted the siege on Liaodong and also ordered the southern offensive to be terminated, returning to Zhuo Commandery while sending Yuwen and Qutu Tong () south to aid Luoyang. The general in charge of defending Chang'an, Wei Wensheng (), also came to Luoyang's aid. Together, these forces outnumbered Yang Xuangan's and dealt him several defeats. Yang Xuangan decided to try to advance west to capture Chang'an as a base of operations, but on the way was again defeated, and he had his brother Yang Jishan () kill him, to avoid capture. At Emperor Yang's orders, the officials Fan Zigai () and Pei Yun () carried out mass-scale reprisals, executing a large number of people who had followed Yang Xuangan. Around the new year 614, by Emperor Yang's orders, Yang Jishan and Yang Xuangan's strategist Wei Fusi () were publicly executed in exceedingly cruel manners—the officials all fired arrows at them, and then they were further drawn and quartered, and then their bodies were burned and the ashes scattered.
