Yang Bin (楊邠) (died December 24, 950), formally the Prince of Hongnong (弘農王) (as posthumously honored during Later Zhou), was a chancellor of the Chinese Five Dynasties and Ten Kingdoms Period Later Han state, serving effectively as the head of the government for most of the reign of its second emperor Liu Chengyou (Emperor Yin), leading a group of high-ranking officials in doing so. However, Liu Chengyou eventually tired of these officials' governance and had Yang killed, along with Shi Hongzhao and Wang Zhang.
It is not known when Yang Bin was born, but it is known that he was from Guangshi (冠氏, in modern Liaocheng, Shandong). In his youth, he became an administrator at the headquarters of the military governor (Jiedushi) of Tianxiong Circuit (天雄, headquartered in modern Handan, Hebei), whose capital Wei Prefecture (魏州) Guanshi belonged to. His wife Lady Kong's paternal uncle was the prominent Later Tang official Kong Qian, who, during the reign of Later Tang's first emperor Li Cunxu, served as the director of material pricing (租庸使, Zuyongshi). During Kong's tenure as the director of material pricing, he made Yang an escort officer, and subsequently, Yang successively served as the food supply officer for three prefectures: Meng (孟州, in modern Luoyang, Henan), Hua (華州, in modern Weinan, Shaanxi), and Yun (鄆州, in modern Tai'an, Shandong).
Later, during the succeeding Later Jin, when the major general Liu Zhiyuan became the defender of Yedu (鄴都, i.e., Wei Prefecture), Liu made Yang one of his guard commanders. When Liu was subsequently moved to be the defender of Taiyuan, Yang apparently followed Liu to his new post, and became a close confidant of Liu's.
Around new year 947, Later Jin's northern neighbor, the Khitan Liao dynasty captured Later Jin's capital Daliang, ending Later Jin. Most Later Jin military governors initially reacted by submitting to Liao's Emperor Taizong as emperor, as Emperor Taizong claimed to be the emperor of central China as well. Liu Zhiyuan initially postured the same way, but his followers, including Yang Bin and Guo Wei, urged him to take imperial title himself. He soon did (as the emperor of a new state that would later be known as Later Han), and, after doing so, made Yang his acting chief of staff (Shumishi).
Meanwhile, Liao's Emperor Taizong, faced with Han Chinese resistance to his rule, left Daliang and intended to return to Liao proper, but died on the way, and was succeeded by his nephew Emperor Shizong, who continued back to Liao proper (to fend off a succession challenge by Emperor Taizong's younger brother Yelü Lihu). Liao generals in the Central Plains region initially continued to try to hold the territory, but gradually lost control due to the Han resistance. Liu launched his army, with Shi Hongzhao serving as his forward troop commander, intending to take the Luoyang-Daliang region, but after Shi initially was bogged down in a siege of Ze Prefecture (澤州, in modern Jincheng, Shanxi), considered recalling Shi. It was after Yang and Su Fengji opposed it (based on the rationale that if he showed weakness, the prefectures that already showed willingness to submit to him would rethink their positions, and Liao might be able to recover from the losses) that he rethought the plan, and, after consulting Shi further, allowed Shi to continue the campaign. (Shi was eventually able to get Ze's prefect Zhai Lingqi (翟令奇) to submit, allowing Shi to continue to advance to Luoyang and get the region to submit to Liu.) After Liu entered Luoyang, he made Yang permanent chief of staff. Liu entrusted the matters of the military to him and Guo, and the matters of government to Su Fengji and Su Yugui.
Shortly thereafter, Du Chongwei, the Liao-commissioned military governor of Tianxiong, who had submitted to Later Han, rebelled when Liu tried to move him to Guide Circuit (歸德, headquartered in modern Shangqiu, Henan). Liu sent the general Gao Xingzhou to command the Later Han troops against Du, with Liu's half-brother Murong Yanchao serving as Gao's deputy. Disputes soon rose between Gao and Murong over strategy: Gao wanted to surround the city and wear out Du's troops, while Murong wanted to immediately siege the city, and went as far as claiming that Gao's refusal to attack immediately was due to a marriage between Gao's daughter and Du's son. With Gao and Murong having disagreement, Liu decided to personally head to Yedu to oversee the campaign. When he arrived there, Gao continued to advocate the slow siege strategy, wanting to wear out the city's food supply and pointing out that the city was well-defended, so an aggressive attack would cause many casualties. With Murong continuing to accuse him, he also went to Su Fengji and Yang to plead his case, stuffing feces and dirt into his mouth as he was doing so, to emphasize the humiliation he had undergone at Murong's hands. After Yang and Su Fengji reported this to Liu, Liu believed Gao, went to his tent to thank him, and rebuked Murong. (Gao's strategy would eventually force Du into surrendering.)
In spring 948, Liu Zhiyuan fell deathly ill. When he did so, Yang became apprehensive about Liu's younger brother Liu Xin (劉信), who was both an imperial guard cavalry commander and the military governor of Zhongwu Circuit (忠武, headquartered in modern Xuchang, Henan), and sent Liu Xin away from the capital (in tears) without allowing him to see the ill emperor. When Liu Zhiyuan came close to death, he entrusted his younger son Liu Chengyou to Su Fengji, Yang, Shi, and Guo, stating, "My remaining breaths are getting short, and I cannot speak much. Chengyou is young and weak, so what happens after my death has to be entrusted to you." He also told them to guard against Du. After Liu Zhiyuan died the same day, these officials, without announcing his death, had Du and his sons put to death. Liu Chengyou was created the Prince of Zhou, and shortly after, when Liu Zhiyuan's death was announced, Liu Chengyou succeeded him as emperor.
Early in Liu Chengyou's reign, the high-level officials were in a collective leadership, with different responsibilities. Yang Bin oversaw the governmental operations; Guo Wei oversaw military operations; Shi Hongzhao oversaw the imperial guards; and Wang Zhang oversaw the financial agencies. Su Fengji, Su Yugui, and Dou Zhengu served as chancellors. However, when the chancellors, led by Su Fengji, wanted to promote officials and fill unfilled positions, Yang saw the requests as wasteful and often rejected them, causing the chancellors to be displeased. In spring 948, one of the chancellors, Li Tao, submitted a petition to Liu Chengyou suggesting that Yang and Guo (who was then deputy chief of staff) be given military commands outside the capital and that key matters be decided by Su Fengji and Su Yugui. When Yang and Guo heard of this, they went to see Liu Chengyou's mother (Liu Zhiyuan's wife) Empress Dowager Li, stating to her, "Your subjects have followed the deceased emperor ever since difficult times. Now, the Son of Heaven is accepting other people's word and wants to send us out. Given that there are troubles west of the pass [(i.e., in the Guanzhong region, where the general Wang Jingchong was fostering a rebellion)], how can we, your subjects and ignore the affairs of the state? If we are not to remain, we hope to at least remain until the deceased emperor's burial." Empress Dowager Li was angered, and she went to Liu Chengyou, stating to him, "These are the old and accomplished subjects of the state. Why are you listening to others and expelling them?" When Liu Chengyou blamed the matter on the chancellors in general, Li Tao took the blame by himself, and was relieved of his chancellor position. Subsequently, Yang was given an additional chancellor position, while Guo was made co-chief of staff, such that Yang became the main decision-maker, with the three chancellors no longer having real chancellor authority. Indeed, it was said that even on minor matters, even if the three chancellors concurred, no decision would be carried out unless Yang agreed with it, such that many needed actions became stalled. In particular, Yang, who rose from administrative ranks, disliked people in traditional learning, often stating: "For the state, it is most important that the treasury is full, and the military is strong. Who cares about matters of literature, rites, and music?" Further, as he still resented Su Fengji and Su Yugui (believing that they were behind Li Tao's petition) and also believed that the two Su chancellors had been insufficiently selective in their commissioning of officials, he made the process of commissioning officials to be an arduous one, such that sometimes people who had been promised official positions would not be commissioned for years. Further, those who had received their positions through connections or through seniority were often removed.
