Since the emergence of the profession of eunuch in society, eunuch has always been a poor and hateful synonym. From the beginning of the Eastern Han Dynasty, eunuchs were no longer "complete", and if they wanted to become royal attendants, they basically had to be stabbed first. Therefore, everyone who became a eunuch was mostly a poor and desperate family, but there was no way to set foot on this path. But at the same time, they often accompanied the royal family, and it was easy to gain the trust of the monarch and thus hold great power. And many years of eunuch career, often let them become psychological distortion, once the power, for the imperial court, for the country, is undoubtedly a disaster. The Rebellion of the Ten Constant Attendants of the Eastern Han Dynasty, Liu Jin of the Ming Dynasty, Wei Zhongxian, etc. were all lessons, deepening people's stereotypes of eunuchs and making them "yin and yang" people from then on. However, because of their experiences and particularities, there are indeed many eunuchs who are annoying. But among them, there are also many eunuchs who are great and admirable.
During the Five Dynasties and Ten Kingdoms period, Li Cunxun, the King of Jin, declared himself emperor of WeiZhou. In order to show orthodoxy, he took Li as a glory and Tang as the national name, and listed the three generations of his ancestors with Tang Gaozu, Tang Taizong and others as the Seven Temples, known in history as Later Tang. After that, he first destroyed Hou Liang, occupied the Central Plains, and then launched an attack on the southern states, with the intention of unifying the world.
At that time, Wang Yan, the lord of the Former Shu Dynasty, acted absurdly, making the people of the country unhappy. Li Cunxun seized this opportunity and launched an attack on Former Shu. However, although there were many battles and victories in the early stage, in the later stage, Wang Yan had the heart to die. If it really dragged on, it would be a disaster for the people of Former Shu, and it would not be good for the Tang Army. To this end, former Shu Zhongshu Order launched a coup d'état, imprisoned Wang Yan, and negotiated with the Tang army in the name of Wang Yan. During the negotiations, The former Shu received Li Cunxun's assurance that as long as they surrendered, they would never kill Wang Yan's family and enjoy eternal glory and wealth, and Wang Yan and his party immediately surrendered the city. The occurrence of this incident made the Tang Army's prestige spread everywhere, and it even frightened the southern countries.
However, Li Cunxun was not happy for long, but there was a problem within the Tang Army. First, he mutinied in Bei Prefecture and invaded Wei Prefecture. Immediately, Xingzhou and Cangzhou also mutinied under this evil wind. For a time, the situation in the Tang army was greatly reversed, and Li Cunxun fell into an extremely embarrassing situation. In order to prevent Wang Yan from also taking advantage of the situation to defect, Li Cunxun decided to kill Wang Yan before the civil unrest in the country. In the edict, he adhered to the attitude of cutting grass and removing roots, and he wanted to kill not only Wang Yan, but also more than a thousand people who accompanied Wang Yan.
Li Cunxun's rebellion was really undeserved, and now he had to be buried with more than a thousand innocent people, which made the eunuch Zhang Juhan who passed on the message unbearable. In order to save these innocent people, he risked killing his head and changed the "line" in the edict to a "home". And this small change also allowed more than a thousand people to survive, only Wang Yan's family suffered.
It was not until several years after Zhang Juhan's death that the matter was revealed. When Ouyang Xiu made a biography for the eunuch, he highly praised his benevolence, which is something that many able-bodied people can't do!
