Before Zhu Ci's rebellion Emperor Daizong died in 779 and was succeeded by his son
Emperor Dezong. Emperor Dezong, believing that Guo Ziyi was too lax and had too large of a responsibility area, honored Guo as
Shangfu (尚父, "like an imperial father") but stripped him of his commands. He divided Guo's responsibility area among Li Huaiguang, Hun Jian, and Chang Qianguang (常謙光), making Hun the military governor of Zhenwu Circuit (振武, headquartered in modern Hohhot), governing the bases and prefectures on the northern border with Huige. Later in the year, however, when
Cui Ning was made the military governor of Shuofang Circuit, Zhenwu was merged back into Cui's command, and Emperor Dezong recalled Hun to serve as a general of the imperial guards, as one of the two generals in charge of security at Chang'an. In 783, after
Li Xilie, the military governor of Huaining Circuit (淮寧, headquartered in modern
Xuchang,
Henan) rebelled, Li Xilie forged letters from Hun, hoping to falsely implicate Hun in the rebellion. Hun defended himself against charges when the letters were intentionally left for imperial authorities to find, and Emperor Dezong, believing him, not only did not punish him but awarded him with a horse and silk, and made him part of the army staff against Li Xilie. Subsequently, Zhu Ci claimed the title of emperor of a new state of Qin, and he put Fengtian under siege. It was said that during the siege, Hun and Han Yougui (韓遊瓌) had to fight day and night without rest to fight off the Qin troops. With the siege continuing and Qin forces sieging Fengtian on three sides, but Fengtian's defenses holding, Emperor Dezong, apparently to reward Hun, added the Weinan (渭南, i.e., the region south of the Wei River) region, as well as Jin (金州, in modern
Ankang,
Shaanxi) and Shang (商州, in modern
Shangluo,
Shaanxi) Prefectures to his responsibility. However, in the aftermaths of Fengtian's siege being lifted, Emperor Dezong offended Li Huaiguang by refusing to meet him and sending him, along with other generals
Li Sheng, Li Jianhui (李建徽), and Yang Huiguang (楊惠光), toward Chang'an to combat Zhu. In spring 784, Li Huaiguang rebelled as well, and when Hun received the news, he put army accompanying Emperor Dezong on high alert and escorted Emperor Dezong safely to Liang Prefecture (梁州, in modern
Hanzhong,
Shaanxi). Eventually, though, with Li Huaiguang's subordinates turning against him, Li Huaiguang withdrew to Hezhong (河中, in modern
Yuncheng,
Shanxi), allowing Li Sheng to prepare to attack Zhu. Emperor Dezong made Hun the military governor of Shuofang Circuit and gave him the honorary
chancellor designation
Tong Zhongshu Menxia Pingzhangshi (同中書門下平章事). When Emperor Dezong bestowed these offices on Hun, he held an elaborate ceremony intended to emulate the ceremony that
Emperor Gao of Han held for
Han Xin when making Han the commander of his army.
After Zhu Ci's rebellion Before returning to Chang'an, Emperor Dezong made Hun Jian
Shizhong (侍中), the head of the examination bureau of government (門下省,
Menxia Sheng) and a post considered one for a chancellor. In the subsequent celebration of the victory of Zhu Ci, when Emperor Dezong was honoring the generals, Li Sheng was honored first, and Hun was honored second. Subsequently, Emperor Dezong made Hun the military governor of Hezhong Circuit, then under Li Huaiguang's control, intending to have him attack Li Huaiguang. In 787, during the middle of a major Tufan incursion, Li Sheng, Hun, and Ma all led forces against Tufan, but Tufan's chancellor
Nanam Shang Gyaltsen Lhanang ("Shang Jiezan" (尚結贊) in Chinese) convinced Ma that he was interested in peace, and Emperor Dezong agreed to make peace despite Li Sheng's opposition. Per Shang's request, Emperor Dezong sent Hun, as his emissary, to meet Shang at Pingliangchuan (平涼川, in modern Pingliang). Li Sheng, fearing Tufan treachery, instructed Hun to be careful, but Zhang, hearing this, accused Li Sheng of interfering with the peace with Tufan. Emperor Dezong thus instructed Hun to be relaxed and not to aggravate Tufan in any way. On July 8, 787, at the meeting site, Shang laid a trap for Hun and launched a sudden attack, killing and capturing many of Hun's attendants, but Hun escaped. Subsequently, joining forces with Han and Luo Yuanguang (駱元光), they were able to hold off a Tufan assault on Chang'an. He died on January 1, 800, and was mourned and buried with great honor. It was said that Hun was studious, and understood the
Spring and Autumn Annals and the
Book of Han well. Imitating the style of the autobiography of
Sima Qian (the author of the
Records of the Grand Historian), he wrote a record of his own campaigns, in which he described his campaigns plainly without bragging. Despite his great accomplishments, he remained humble and careful in serving the emperor, and whenever he received imperial rewards, he would always kneel to receive them. The popular opinion at the time compared him to
Jin Midi of the
Han dynasty. After Zhu Ci's rebellion, Emperor Dezong often feared rebellions by generals and would often appease them by agreeing to all of their requests, but did not do so with Hun. Hun was pleased by this and stated, "The Emperor does not suspect me!" == Notes and references ==
