Li Zhang, the head of the Record Office, beat a petty official of the Ya army with a cudgel. The next day, more than a hundred Ya soldiers came to Lu Jun to lodge a complaint. Lu Jun used a cudgel to beat the leader among them and banished him to a distant town to guard the frontier. The rest of the soldiers were also punished. Lu Jun said: "More than a hundred men from the border town came to lodge a complaint without reason. Such arrogance cannot be tolerated."
