withdrew from Shen Prefecture, although Wang continued to put Shen Prefecture under siege, forcing Niu to eventually fight his way out of the siege. In summer 822, Zhu submitted a tribute of horses and goats to the imperial government — but as part of the tribute, demanded rewards for his soldiers. It is not clear how the imperial government reacted. During Emperor Jingzong's reign In 826, by which time Emperor Muzong's son Emperor Jingzong was emperor, there was an occasion when imperial eunuch messengers were delivering new uniforms to the circuits. When the uniforms reached Lulong Circuit, Zhu Kerong complained that the uniforms were of low quality and detained the eunuchs. At that time, Emperor Jingzong was originally intent on visiting the eastern capital Luoyang and restoring the early Tang customs of the emperor spending time in both the main capital Chang'an and Luoyang. Both Wang Tingcou and Zhu sent arrogantly-worded offers to contribute troops to repair the long-ruined palaces and governmental offices at Luoyang, offers that Emperor Jingzong declined, and Emperor Jingzong subsequently abandoned the plan to visit Luoyang, at the urging of Pei Du, who was then chancellor. Zhu also demanded silk and claimed that the soldiers would clamor to rebel if he did not receive silk. Emperor Jingzong was angered, but at Pei's urging sent edicts with kind words to calm Zhu, and created him the Prince of Wuxing. In summer 826, the Lulong soldiers mutinied and killed Zhu Kerong and his son Zhu Yanling. In the aftermaths, soldiers supported his younger son Zhu Yansi to take over the circuit. Later in the year, however, the officer Li Zaiyi killed Zhu Yansi and slaughtered the Zhu household — some 300 people. Notes and references Old Book of Tang, vol. 180. New Book of Tang, vol. 212.
