The Feng-cheng Marquis Li Bin, regional commander of Jiao-zhi, memorialized: "The Jiao-zhi bandit Ruan Zhen and others who had repeatedly assembled forces in Lu-na County and killed and plundered people and livestock, have been captured. In accordance with the law, Zhen should be executed and his wives and children given as slaves to the families of meritorious officials. It is requested that it be permitted to execute him in the region as a warning to the people, so that they will know fear." This was approved.
