Wang Du
In summer 928, Emperor Mingzong ordered a general campaign against Wang Du, putting Wang Yanqiu in overall command of the operations, assisted by An Shentong () and Zhang Qianzhao (). Wang Yanqiu quickly advanced to Ding Prefecture and put it under siege, but the Khitan general, the Xi chieftain Tunei () quickly arrived to aid Wang Du. They attacked Wang Yanqiu, but Wang Yanqiu repelled their attack, forcing them to withdraw within the Ding city walls. Wang Yanqiu then captured Ding's western city. However, the main city's walls were secure and difficult to attack, so Wang Yanqiu relaxed his attack, while building a temporary Yiwu headquarters (as Emperor Mingzong put him temporarily in charge of Yiwu), collecting the taxes from the three prefectures (Ding, Qi, and Yi) to supply his troops.
