秦宗權
Sun Ru (; died July 3, 892), formally the Prince of Le'an (), was a Chinese military general and politician during the Tang Dynasty. He initially served as a general under the pretender emperor Qin Zongquan. After Qin's defeat, he nominally submitted to Tang imperial authority and contended for control of the central-lower Yangtze River region with Yang Xingmi; he was eventually defeated by Yang and executed. His subordinate Ma Yin was the eventual founder of the Five Dynasties and Ten Kingdoms period state Chu.
