Murong Bao, although aware of Empress Duan's earlier suggestion to make Murong Nong or Murong Long crown prince (and in fact was so resentful of it that he forced her to commit suicide), appeared to trust his brothers greatly, and he made Murong Nong the viceroy of Bing Province (并州, modern central and northern Shanxi) to guard against a Northern Wei attack. However, Murong Nong immediately made the mistakes of collecting food for his troops—too much for the local population, then suffering from a famine, to support—and sending military officers to watch over non-Han tribes. The people became resolved to revolt, and they sent messengers to Northern Wei, requesting Tuoba Gui to advance on Bing Province. In late fall 396, he arrived at the capital of the province, Jinyang (晉陽, in modern Taiyuan, Shanxi), and when Murong Nong engaged Tuoba Gui in battle, Tuoba Gui defeated him, and he was forced to flee back to Zhongshan, but his wife and children were captured by Northern Wei and he himself was wounded.
