Dong Zhang
In spring 924, Khitan forces made an incursion into Lulong territory, going as deep into Later Tang as Waqiao Pass (瓦橋關, in modern Baoding). Li Cunxu sent Li Siyuan to command an army against the Khitan forces, with Huo Yanwei, now a Later Tang general, as his deputy. However, soon thereafter, Khitan forces withdrew, so he recalled Li Siyuan, instead leaving Duan Ning — now bearing the imperially-bestowed name of Li Shaoqin — and Dong Zhang at Waqiao Pass to defend it. Shortly after, though, there was yet another report of a Khitan incursion, so Li Siyuan was ordered to stop at Xing Prefecture (邢州, the capital of Anguo Circuit) to see if the Khitan would attack, while Li Congke and Li Shaobin were ordered to command cavalry forces to defend against the attack as well. Around this time, Li Siyuan, who, like other generals, feared false accusations by Li Cunxu's favored eunuchs and actors, sought to be relieved of his command, but Li Cunxu did not accept his resignation.
