Ma Yin
In 904, Yang realized that Ma Cong, who remained at Huainan and served in his army for a number of years after Yang defeated Sun Ru, was Ma Yin's brother. He offered to send Ma Cong to Ma Yin. Ma Cong initially declined, indicating that he was grateful for Yang's not killing him at the time of Sun's death and making him a Huainan officer, but Yang insisted. After Ma Cong arrived at Tan, Ma Yin made him the deputy military governor. Ma Cong subsequently advocated an alliance between Ma Yin and Yang, but Ma Yin rejected Ma Cong's proposal.
