Yang Xuangan, an official of China’s Sui Dynasty, mindful that Emperor Yang is apprehensive of his father, the powerful official Yang Su, rebels near the eastern capital, Luoyang, but is soon defeated.

He orders his brother Yang Jishan to kill him, so as to not fall into Emperor Yang's hands.

Emperor Yang crosses the Liao River again and puts Manchuria under siege in summer 613.

However, at this time, news arrives that Yang Su's son Yang Xuangan had rebelled near Luoyang.

With the people disaffected by the Goguryeo campaigns, Yang Xuangan receives much popular support and threatens Luoyang.

Emperor Yang, in fear, lifts the siege on Liaodong and also orders the southern offensive to be terminated, returning to Zhuo Prefecture while …

…sending Yuwen and Qutu Tong south to aid Luoyang.

The general in charge of defending Chang'an, Wei Wensheng, also comes to Luoyang's aid.

Together, these forces outnumber Yang Xuangan's and deal him several defeats.

Yang Xuangan decides to try to advance west to capture Chang'an as a base of operations, but on the way is again defeated, and he has his brother Yang Jishan kill him, to avoid capture.

At Emperor Yang's orders, the officials Fan Zigai and Pei Yun carry out mass-scale reprisals, executing a large number of people who had followed Yang Xuangan.
