the pardons, Wang Wujun, Tian Yue, and Li Na renounced their princely titles and reclaimed allegiance to Tang; in turn, Emperor Dezong made them military governors of their own circuits. However, Li Xilie reacted by declaring himself the emperor of a new state of Chu, while Zhu Tao headed south, attempting to join Zhu Ci. When Tian refused to join him, he attacked Weibo, but was unable to immediately capture it. With Tian Yue subsequently assassinated and succeeded by his cousin Tian Xu, Zhu Tao initially attempted to persuade Tian Xu to join him, but Tian eventually reentered an alliance with Wang and Li Baozhen and resisted Zhu Tao. Wang and Li Baozhen soon arrived and defeated Zhu Tao, forcing him to flee back to Lulong. Meanwhile, though, Li Huaiguang, disaffected from Emperor Dezong, was in secret negotiations with Zhu Ci (who had changed his state's name to Han by this point) to enter an alliance with Zhu. Zhu promised to honor Li Huaiguang as an elder brother and divide the Guanzhong region with him, with each ruling a state as its emperor. On March 20, Li Huaiguang declared his rebellion and alliance with Zhu. Emperor Dezong fled from Fengtian to Liang Prefecture (梁州, in modern Hanzhong, Shaanxi). Several key officers under Li Huaiguang—including Han Yougui (), Dai Xiuyan (), Luo Yuanguang (), and Shang Kegu ()—however, refused to follow Li Huaiguang and instead accepted commands from Li Sheng, whom Emperor Dezong made the commander of Tang forces in the region. With Li Huaiguang weakened, Zhu no longer treated him with respect but instead as a subordinate. In anger and fear, Li Huaiguang withdrew from the region and headed back to his base at Hezhong (河中, in modern Yuncheng, Shaanxi). Li Sheng soon prepared for a final attack on Chang'an, and he launched his attack on June 12. On June 20, with Li Sheng having entered the city, Zhu Ci fled toward Tufan. He was soon killed in flight by his own soldiers, ending his state of Han. On August 3, Emperor Dezong returned to Chang'an. When he sent emissaries to persuade Li Huaiguang to again pledge allegiance to him, Li Huaiguang was initially receptive, but when Emperor Dezong's further emissary, the official Kong Chaofu (), arrived at Hezhong, Li Huaiguang's soldiers, believing that Kong was showing disrespect to Li Huaiguang, killed Kong, apparently with Li Huaiguang's implicit approval, and
