Background and career under Emperors Daizong, Dezong, and Shunzong

Xue Ping was born in 753, during the reign of Emperor Xuanzong. When he was 11, during the reign of Emperor Xuanzong's grandson Emperor Daizong, he was made the prefect of Ci Prefecture (磁州, in modern Handan, Hebei), one of the prefectures then under the rule of his father Xue Song, the military governor (Jiedushi) of Zhaoyi Circuit, a former general of the rebel Yan state of the Anshi Rebellion who submitted to Tang Dynasty rule in the aftermaths of Yan's collapse but who thereafter ruled Zhaoyi Circuit semi-independently from the imperial government.

When Xue Song died in 773, the soldiers demanded that Xue Ping inherit the command of the circuit. Xue Ping initially pretended to agree, but then yielded the command to his uncle Xue E and, in the middle of the night, took his father's casket and fled back to his father's ancestral home of Jiang Prefecture (絳州, in modern Yuncheng, Shanxi). Xue E subsequently was unable to stand against the attacks by the neighboring warlord Tian Chengsi the military governor of Weibo Circuit (魏博, headquartered in modern Handan) and forced to flee; part of Zhaoyi Circuit was merged into Weibo Circuit and part was merged with the imperially-controlled Zelu Circuit (澤潞, headquartered in modern Changzhi, Shanxi), with the newly constituted circuit still named Zhaoyi. Meanwhile, after Xue Ping completed his period of mourning for his father, Emperor Daizong made him a general of the imperial guards — where he stayed for over 30 years.

Career under Emperors Xianzong and Muzong

Later, during the reign of Emperor Daizong's great-grandson Emperor Xianzong, the chancellor Du Huangchang believed that Xue Ping was talented and recommended him to be the prefect of Ru Prefecture (汝州, in modern Pingdingshan, Henan), and Xue governed with distinction. By 812, Xue was referred to as a major general of the imperial guards, when he was made the military governor of Yicheng Circuit (義成, headquartered in modern Anyang, Henan) in the aftermaths of the death of the warlord Tian Ji'an (Tian Chengsi's grandson) the military governor of Weibo, as part of the imperial maneuvering to try to control Weibo. (Subsequently, Tian Ji'an's relative Tian Xing (who was later renamed Tian Hongzheng) seized control of Weibo from Tian Ji'an's son Tian Huaijian and submitted to the imperial government.)

While Xue Ping was at Yicheng, he dealt with the issue of Yellow River flooding his circuit — as Yicheng's capital Hua Prefecture (滑州) was just two li (about one kilometer) away from the Yellow River and often suffered from catastrophic floods. Xue Ping conducted surveys and found traces of the old Yellow River bed. After a joint petition he made with Tian Hongzheng (who became the military governor of Weibo), they dug into the old river route for 14 li (about seven kilometers) to divert some of the water from then-route of the Yellow River, and thus decreasing the threat of flooding for Yicheng. Xue was at Yicheng for six years before being recalled to again serve as a general of the imperial guards, but was soon sent back to Yicheng to again serve as military governor.

In 819, after Emperor Xianzong destroyed the warlord Li Shidao, who ruled Pinglu Circuit (平盧, headquartered in modern Tai'an, Shandong), Emperor Xianzong divided Pinglu into three circuits, with the circuit that kept the Pinglu name having its headquarters moved to Qing Prefecture (青州, in modern Weifang, Shandong). He made Xue the military governor of Pinglu, as well as the official in charge of relations with Silla and Balhae. (It was because Xue was familiar with the customs of the region north of the Yellow River and his faithfulness to the imperial government that, when, in 821, by which time Emperor Xianzong's son Emperor Muzong was emperor, Liu Zong the military governor of Lulong Circuit (盧龍, headquartered in modern Beijing), which had also long been ruled independently from the imperial government, surrendered Lulong to imperial control, Liu recommended dividing Lulong into three circuits with Xue, the former chancellor Zhang Hongjing, and the official Lu Shimei (盧士玫) taking the commands of the three circuits, although Liu's recommendations were not heeded, and the command of Lulong was given to Zhang with only a small portion carved out and given to Lu.)

Later in 821, the Lulong soldiers rebelled against Zhang and arrested him, and soon thereafter, the Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei) soldiers also rebelled and killed Tian (who had been transferred to Chengde). In the aftermaths, the imperial government waged an ultimately unsuccessful campaign against Lulong and Chengde, and during the campaign, the rebels threatened Di Prefecture (棣州, in modern Binzhou, Shandong) of Pinglu's neighboring Henghai Circuit (橫海, headquartered in modern Cangzhou, Hebei). Xue sent his officer Li Shuzuo (李叔佐) to help defend Di Prefecture, but when Wang Ji (王稷) the prefect of Di Prefecture did not supply the Pinglu soldiers to their satisfaction, the soldiers mutinied and supported the officer Ma Tingfu as their leader and returned to Qing Prefecture to attack it. At that time, Qing Prefecture had few troops and could not defend against the attack, but Xue expended both the circuit treasury and his own wealth to hire some 2,000 soldiers, and with these soldiers he defeated and killed Ma. As a result, Emperor Muzong gave Xue the honorary title of You Pushe (右僕射) and created him the Duke of Wei.

Career under Emperors Jingzong and Wenzong

Xue Ping remained at Pinglu for six years, and it was said that he prepared the troops well and taxed in a fair manner. When, in 825, during the reign of Emperor Muzong's son Emperor Jingzong, Xue was set to go to the capital Chang'an to pay homage to Emperor Jingzong and remain there, the residents were said to be so saddened that they tried to block his way to stop him from leaving. When he arrived at Chang'an, he was briefly made the minister of census (戶部尚書, Hubu Shangshu) and acting Zuo Pushe (左僕射), one of the heads of the executive bureau of government (尚書省, Shangshu Sheng). In a month, however, he was commissioned as the military governor of Hezhong Circuit (河中, headquartered in modern Yuncheng) and acting Sikong (司空, one of the Three Excellencies). In 828, after two prefectures were added to his circuit, he was further made acting Situ (司徒, also one of the Three Excellencies); his title was also changed to Duke of Han. He was recalled in 830 to serve as senior advisor to the Crown Prince. He requested retirement in 831 and was allowed to do so. He died in 832 and was given posthumous honors.

生平

十二歲時，以父親的緣故，官拜磁州（今河北磁縣）刺史。唐代宗大曆八年（773年）正月，薛嵩逝世，昭義軍內部軍吏想要擁立十七歲的薛平繼承父親官位，薛平假裝同意，實際卻將官位讓給了叔父薛㟧。喪期滿後，授右衛將軍，宿衛三十年。宰相杜黃裳擢升其為汝州刺史、御史中丞，「理有能名」「治有風績」。唐元和七年（812年），朝廷對淮西用兵，薛平以左龍武大將軍兼受御史大夫、滑州刺史、鄭滑節度觀察使，作戰累有戰功。

滑州（今河南滑縣）往西，距離黃河僅二里路程，每年都常常遭受水患。薛平訪問探查得知古河道，與魏博節度使田弘正同時上書，開通南北長十四里的古河，掘開舊河分攤河水，自此滑州人再無水患。在鎮六年，入朝為左金吾衛大將軍。不久又官拜鄭華節度觀察使。唐朝平定李師道，政府以東平十二州為三道，將淄州、青州、齊州、登州、萊州等五州為平盧軍，以薛平為平盧軍節度使、觀察使等，「仍押新羅、渤海兩蕃使」。

長慶元年（821年），幽鎮叛，杜叔良統帥橫海軍討伐，未能取勝。棣州（今山東惠民東南）又遭受叛軍圍困，唐朝廷命薛平帥偏師援救棣州，于是薛平派遣將軍李叔佐領兵救援。幾個月後，棣州刺史王稷供給士兵的糧食等減少，士卒多有怨言，李叔佐不能制止，當晚兵敗而歸。叛亂士卒共推「突將」馬狼兒為統帥。沿途劫掠屯鎮，兵力達到七千餘人，緊逼青州城（今山東益都）。形勢危急之下，薛平盡出府庫及家中資財，招募精兵二千，大破敵軍。加封右僕射，進封魏國公，威名遠揚。

薛平在鎮六年，「兵甲完利，井賦均一」，以至于入朝時，百姓「遮道乞留」，好幾日後才出去。寶曆元年，回朝後進封檢校左僕射，兼任戶部尚書。一個月後又檢校司空，兼任河中絳隰節度觀察等使。大和二年，將晉州、慈州歸于河中管轄之下。加拜薛平為檢校司徒。薛平在河中六年，後拜為太子太保。第二年以司徒的官職結束為官生涯。一年後（即開成元年，公元836年）逝世，年八十歲，追贈太傅。
