In the second year Dazhong (848 CE) Counsellor to the Board of Punishments Xing Qun was residing in Luozhong, having previously served as the provincial governor of Shezhou. He fell seriously ill. Qun had long been friendly with the Imperial Censor Zhu Guan. At that time Guan had left office in the Huai-Hai area to reside in Yiluo, but had then fallen ill and died. Qun was not aware of this, however. Lying down one day, he suddenly heard someone knocking on his door, so ordered it be answered. Seeing Guan arriving on horseback, Qun invited him to enter and sit. Prior to this Qun had heard that Guan had been unwell, and was delighted to see him visit. He said: “Having been informed the gentleman was ill, we express our humble concern.” Guan said: “Your servant was unwell, but has now recovered, but for the gentleman’s illness we express our humble concern. It shouldn’t be more than a day or two before you hear of me.” They talked and laughed together before he departed. When Guan called on Qun, Guan must already have been dead.
