An Chonghui
ngIn 926, Emperor Zhuangzong was killed in a mutiny at then-capital Luoyang. Soon, his adoptive brother, the general Li Siyuan, who had led a separate mutiny, arrived at Luoyang and claimed imperial title (as Emperor Mingzong). Emperor Mingzong bestowed the honorary chancellor title of "Zhongshu Ling" () on Wang Du, but was said to despise Wang because of what Wang had done to his father. Another source of the friction between the imperial government and Yiwu developed over the fact that Emperor Mingzong's chief of staff An Chonghui wanted to show imperial strength and was not as willing to allow Yiwu to retain its revenues. Further, due to the incessant Khitan attacks, the Later Tang imperial government was often sending armies to the region of Lulong and Yiwu, and Wang feared that they actually intended to attack him. Both sides became suspicious of each other.
