Wang Du
However, Wang Du was, for months, effective at holding Ding's defenses. He also kept close watch on his officers, and any officer who were about to defect to the imperial forces would be killed. Emperor Mingzong sent messengers to push Wang Yanqiu into attacking more directly, but Wang Yanqiu showed the secureness of the defenses to the imperial messengers, and insisted that it was better to keep the city under siege and then wait for it to collapse on its own. Emperor Mingzong agreed. In spring 929, Wang Du and Tunei tried to fight their way out of the siege, but could not. Shortly after, Wang Du's officer Ma Rangneng () opened up the city gates to let the imperial forces in. Wang Du and his family committed suicide by fire. Wang Du had maintained an extensive collection of books, which he collected by sending messengers to buy up rare books at the time that Zhang Wenli's son Zhang Chujin was defeated at Chengde, and when Later Liang was conquered. In his suicide, the book collection was also destroyed. Four of his sons and one of his brothers (presumably from the Liu line) were captured (along with Tunei) and presented to Emperor Mingzong.
