Prince of Hongnong
Yang Wo, believing Xu was advising him out of good faith, wept and thanked him. In 905, when Yang Xingmi became even more ill, he was set on summoning Yang Wo back from Xuan Prefecture and entrusting the affairs of the circuit to him. Yang Xingmi's secretary Zhou Yin (), however, citing Yang Wo's frivolousness, opposed, instead suggesting that Yang Xingmi entrust the circuit to Liu Wei with a promise from Liu to transfer it to another son of Yang Xingmi's. Xu and the other guard commander, Zhang Hao, however, opposed Zhou's proposal, pointing out that Yang had fought these years to leave the state to his family. When Yang Xingmi subsequently issued an order and ordered Zhou to dispatch it to Yang Wo, Zhou did not send it for some time; when Xu and Yan found Yang Xingmi's order still on Zhou's desk, they took it and had it delivered to Yang Wo, who subsequently returned to Yang Prefecture. Yang Xingmi subsequently died, and Yang Wo, with the title of Prince of Hongnong bestowed by Emperor Zhaozong's emissary Li Yan, took over the circuit.
