Guan Bo
Guan Bo , courtesy name Wuyuan, was an official of the Chinese dynasty Tang Dynasty, serving as a chancellor during the reign of Emperor Dezong.
Background
Guan Bo was born in 719, during the reign of Emperor Xuanzong. His family was from Wei Prefecture and claimed ancestry from the late Han Dynasty general Guan Yu. Late in Emperor Xuanzong's Tianbao era, Guan Bo passed the imperial examinations. During the subsequent reign of Emperor Xuanzong's son Emperor Suzong, when the general Deng Jingshan served as the military governor of Huainan Circuit, Deng invited Guan to serve as a secretary under him. Guan subsequently returned to the capital Chang'an to serve in the imperial guard corps, and then as You Bujue, a low-level official at the legislative bureau of government. He was said to be well-versed in philosophy and metaphysics, particularly Buddhist philosophy.During Emperor Daizong's reign
During the Dali era of Emperor Suzong's son Emperor Daizong, Guan Bo had a close association with the imperial guard commander Wang Jiahe and Wang's wife, who was also named Guan. The chancellor Yuan Zai was displeased about this association, and he sent Guan Bo away from the capital, to serve as an officer at Henan Municipality. While at Henan, Guan acted as magistrate of several counties and was said to be capable in his governance. When Chen Shaoyou later served as the governor of Zhedong Circuit and then Huainan Circuit, he invited Guan to serve as his secretary. He later acted as the prefect of Chu Prefecture. When Li Lingyao rebelled against imperial authority in 776 and seized nearby Biansong Circuit, Chen was one of the generals commissioned against Li Lingyao, but as he commanded the troops against Biansong, the bandits in his own circuit were rampaging. Guan mobilized the prefectural militia to defend against the bandits, and also was said to be a simple but effective governor. After Yang Guan and Chang Gun became chancellors in 777 to replace Yuan, they recommended Guan to be Duguan Yuanwailang, a low-level official at the ministry of justice.During Emperor Dezong's reign
Emperor Daizong died in 779 and was succeeded by his son Emperor Dezong. Early in Emperor Dezong's reign, there was a group of bandits who occupied caves in Hunan Circuit, led by Wang Guoliang. Emperor Dezong sent Guan to try to persuade Wang to submit. Before Guan's departure, Emperor Dezong and he had a conversation in which Guan impressed Emperor Dezong with words about finding capable officials. Upon Guan's return from the mission, Emperor Dezong made him Bingbu Yuanwailang, a low-level official at the ministry of defense. He was then made the deputy mayor of Hezhong Municipality.In 781, Guan was recalled to Chang'an to serve as imperial attendant. While serving at that post, he suggested that learned officials be put in charge of the various treasuries, which had previously been overseen by unlearned technicians; it was said that this change was followed later to the benefit of the state. He then served as deputy minister of justice. As Emperor Dezong's trusted chancellor Lu Qi viewed Guan as mild in temperament and easy to control, he repeatedly recommended Guan, who successively served as the minister of civil service affairs and minister of justice.
In 782, with Lu then serving as the only chancellor but knowing that Emperor Dezong, by custom, would want to commission at least one more chancellor, he recommended Guan to be chancellor. Emperor Dezong thereafter made Guan Zhongshu Shilang, the deputy head of the legislative bureau, and gave him the designation Tong Zhongshu Menxia Pingzhangshi, making him a chancellor de facto. He also gave Guan the honorific title Yinqing Guanglu Daifu, made him an imperial scholar, and put him in charge of editing the imperial history. It was said, however, that Lu dominated the government, and Guan did not participate in the decision-making. On one occasion, when Emperor Dezong was meeting with the chancellors, Guan heard a proposal that he considered inappropriate, and was ready to rise and speak against it, Lu gave him a look that caused him to hesitate. After the meeting was over, Lu told him, "I recommended you, sir, because you are solemn and quiet. How would you dare to open your mouth and speak?" Thereafter, Guan rarely spoke.
It was also said, however, that Guan lacked judgment in the characters of others, and he endeared himself to a number of junior officials who bragged about their own abilities, including Li Yuanping, Tao Gongda, Zhang Sun, and Liu Chengjie. With Li Xilie the military governor of Huaixi Circuit then posturing against the imperial government, Guan repeatedly recommended Li Yuanping, who had particularly bragged about his military strategies and impressed Guan. Emperor Dezong thus made Li Yuanping the acting prefect of Ru Prefecture, as Ru Prefecture was close to Huaixi Circuit. When Li Yuanping arrived there, he immediately began reinforcing the defenses — but not realizing that of the laborers that he hired, many were agents that Li Xilie had sent. When Li Xilie attacked, those laborers turned against Li Yuanping, causing Ru Prefecture to fall to Li Xilie. Li Xilie's soldiers seized Li Yuanping and took him to Li Xilie. Li Yuanping, when meeting Li Xilie in fear, could not control his own body, and he defecated and urinated involuntarily. Li Xilie responded, "How does that blind chancellor think lightly of me, that he sent you to try to defend against me!" When Guan heard that Li Yuanping was captured, he still believed that Li Yuanping would find some way to overthrow Li Xilie, even though none of his subordinates believed it. As a result of what happened to Li Yuanping, none of Guan's other associates were given important offices by Emperor Dezong.
In fall 783, soldiers from Jingyuan Circuit, at Chang'an to await deployment to the east, mutinied after not receiving awards that they believed they deserved. Emperor Dezong fled to Fengtian, initially taking only his family members and a small group of eunuchs and imperial guards with him. Lu and fellow chancellor Guan Bo, in the confusion, had to jump over the walls of the office of chancellors, located at the legislative bureau, to catch up with Emperor Dezong. The Jingyuan soldiers supported the general Zhu Ci as their leader, and Zhu soon declared a new state of Qin as its emperor. He put Fengtian under siege. A Tang aid force, commanded by the generals Du Xiquan, Dai Xiuyan, Shi Changchun, and Li Jianhui, was approaching Fengtian and requesting imperial instructions on which way to advance into the city. Guan and the general Hun Jian suggested having the aid force march over Qianling — the hill containing the tomb of Emperor Dezong's ancestor Emperor Gaozong — so that they would have better tactical position. Lu, arguing that doing so was disrespectful, suggested having the aid force march through a valley, despite Hun's protestations that doing so would expose the aid force to catapult attacks by Qin forces. Emperor Dezong agreed with Lu, and subsequently, the aid force was ambushed and, after suffering heavy losses, was forced to withdraw without ever reaching Fengtian. After the major general Li Huaiguang arrived and saved Fengtian from falling, Li Huaiguang demanded the removals of Lu, Bai Zhizhen, and Zhao Zan — demands that were supported by other officials — and Emperor Dezong was forced to agree. Subsequently, the popular sentiment also opined that Guan, as fellow chancellor to Lu during this disaster, should not be allowed to remain as chancellor, and Emperor Dezong made Guan the minister of justice instead, no longer chancellor. Still, officials such as Wei Lun were distressed that Guan remained an important minister, and they wailed, "The chancellor was unable to plan and assist the emperor properly, leading to this situation, but he is allowed to still be minister. This is distressing."
After Zhu's rebellion was suppressed, in 788, Huige's Heguduolu Khan Yaoluoge Dunmohe, who had entered an alliance with Tang, requested permission to marry a Tang princess. Emperor Dezong agreed and sent Guan to escort Emperor Dezong's daughter Princess Xian'an to Huige to marry the khan and to bestow the title of Changshoutianqin Khan on Yaoluoge Dunmohe. Guan was said to be quiet and not lavish on the way, impressing the people of Huigu. After he returned, Emperor Dezong wanted to make him the minister of defense, but he declined on account of illness and offered to resign. Emperor Dezong made him an advisor to the crown prince Li Song, and allowed him to retire. After his retirement, Guan retained few servants and reduced his numbers of horses and wagons, and he spent his retirement in quietness. For this, he was respected by the officials. He died in 797 and was publicly mourned.
