Li Sizhao
In spring 901, Li Sizhao recaptured Ze, which had again fallen to Xuanwu forces. However, in a subsequent major attack by Xuanwu forces, commanded by Shi Shucong (), against Hedong, the Xuanwu forces advanced all the way to Taiyuan and put it under siege. The city almost fell, and it was said that it was due to nightly counterattacks by Li Sizhao and Li Siyuan that the siege was unsuccessful. With Xuanwu forces bogged down by rain and running out of food supplies, Zhu recalled Shi. Further, Zhaoyi Circuit was, for the time being, lost to Zhu, as Meng surrendered to Xuanwu forces during the campaign. Zhu commissioned Ding as Zhaoyi's military governor. Later in the year, Li Keyong did send Li Sizhao and Zhou to capture Xi () and Ci (慈州, both in modern Linfen, Shanxi, not the same prefecture as the one east of the Taihang Mountains) Prefectures, which had become under Zhu's control when Zhu conquered Huguo earlier in 901.
