Fan Yanguang
Around the same time that the campaign against Xichuan and Dongchuan was abandoned, Li executed the main proponent for the campaign, his chief of staff An Chonghui, and sought rapprochement with the two circuits. Meng desired peace with the imperial government, but Dong, because the imperial government had executed his son Dong Guangye () and Dong Guangye's family, rejected it, and further renounced his alliance with Meng and attacked Meng. Wang notified the imperial government of this, Li's new chief of staff Fan Yanguang suggested to him that this was the time to act against the two circuits while they were fighting with each other, so Li ordered Wang to begin planning for such a campaign. However, shortly after, Meng defeated Dong, who was then killed by his subordinates, and Meng took over Dong's realm. The imperial government thereafter abandoned further designs on the two circuits, as Meng nominally resubmitted to the imperial government as a vassal. Wang was thereafter returned to Chang'an to serve as its defender.
