Liu Yin
Also in 910, Pang Juzhao () the military governor of Ningyuan Circuit (寧遠, headquartered in modern Yulin, Guangxi), and Liu Changlu () the defender of Gao Prefecture (高州, in modern Maoming, Guangdong), who had just recently repelled an attack by Liu Yin but believed that they had no strength to stand against Liu Yin long term, wrote to Ma, offering their territory to hi. Ma sent Yao Yanzhang () to their territory to escort them to Chu proper. He had Yao serve as the prefect of Ningyuan's capital Rong Prefecture () to defend the territory, and subsequently had him made the deputy military governor of Ningyuan. However, in 911, when Liu Yin attacked again, Yao judged the situation untenable despite a relief force commanded by Xu. He therefore took the people of Rong Prefecture and returned to Chu proper, allowing Liu Yin to take over Rong and Gao Prefectures. Despite this setback, Emperor Taizu still bestowed on Ma the titles of military governor of Wu'an, Wuchang, Jingjiang, and Ningyuan, as well as the commanders of the forces against Hong and E (鄂州, Wuchang's capital) Prefectures. However, not wanting to see prolonged warfare between Ma and Liu Yin, both of whom were his vassals, he sent a number of emissaries to try to broker peace between them.
