Prince of Hongnong
Yang Xingmi died in 905. Yang Wo succeeded him as the Tang military governor ("Jiedushi") of Huainan Circuit (淮南, headquartered in modern Yangzhou, Jiangsu) and the effective ruler of rest of Yang Xingmi's domain, which effectively became an independent state after rival warlord Zhu Quanzhong seized the Tang throne and declared himself emperor of a new state of Later Liang in 907—although Yang Wo continued to use the Tang era name of "Tianyou" and thus his domain remained technically a part of the defunct Tang state. He carried the title of Prince of Hongnong, which had been bestowed by the Tang imperial emissary Li Yan. He honored his mother Lady Shi as Lady Dowager.
