|Official of Liu Bei|
|Courtesy name||Xianhe (traditional Chinese: 憲和; simplified Chinese: 宪和; pinyin: Xiànhé; Wade–Giles: Hsien-he)|
Jian Yong (birth and death dates unknown), courtesy name Xianhe, was an official serving under the warlord Liu Bei in the late Eastern Han Dynasty. Jian Yong served under Liu Bei since the very beginnings of Liu's career, acting as a messenger or emissary for his lord. Jian Yong was also known for being a very persuasive speaker and for his carefree personality.
Jian Yong was a native of Zhuo commandery (涿郡), which is in present-day Zhuozhou, Hebei. His original family name was "Geng" (耿), but in his native You Province (Zhuo commandery was in You Province), "Geng" was pronounced the same as "Jian", so he changed his surname. He was an old acquaintance of Liu Bei and later became a subordinate of the latter. When Liu Bei was taking shelter in Jing Province in the 200s, Jian Yong, along with Mi Zhu and Sun Qian, served as "Assistant Officers of the Household" (從事中郎) under Liu Bei. They usually played the roles of messengers or emissaries for Liu Bei.
In 211, when Liu Bei entered Yi Province (covering present-day Sichuan and Chongqing) under the pretext of helping its governor Liu Zhang defend his jurisdiction against a rival warlord Zhang Lu, he sent Jian Yong as an emissary to meet Liu Zhang. Liu Zhang favoured Jian Yong. Later, when war broke out between Liu Bei and Liu Zhang, and Liu Bei had gained the upper hand against his rival and was besieging Yi Province's capital Chengdu, Jian Yong was sent to persuade Liu Zhang to give up resistance. Liu Zhang agreed, and, with Jian Yong by his side, he rode out of the city in a chariot to surrender. After occupying Yi Province and setting up his new base in Chengdu, Liu Bei promoted Jian Yong to the position of "General of Illustrious Virtue" (昭德將軍).
Jian Yong was known for being an excellent debater and speaker. He was carefree in his ways and showed little regard for formalities. When he sat down beside Liu Bei, he behaved boldly, ignored proper etiquette and sat in a manner to make himself feel comfortable. When he attended banquets hosted by Zhuge Liang, he would occupy an entire couch, recline on a pillow and speak to others in a lying down position. He would not condescend to anyone.
Once, there was a drought in Yi Province and a law prohibiting alcohol went into effect. People who brew alcoholic drinks would be punished. Over-zealous officials seized brewing utensils from families and suggested to punish the owners of the utensils as if the owners were as guilty as brewers. When Jian Yong and Liu Bei was inspecting the land, they saw a couple walking past, and Jian said to his lord, "They're planning to commit an indecent act. Why not arrest them?" Liu Bei asked, "How do you know?" Jian Yong replied, "They're equipped with the tools to do so, just as the owners of brewing utensils have the tools to brew alcoholic drinks." Liu Bei laughed and pardoned the families who owned brewing utensils. Such was Jian Yong's wittiness.
Chen Shou, who wrote Jian Yong's biography in Records of the Three Kingdoms, commented as follows: "Mi Zhu, Sun Qian, Jian Yong and Yi Ji were refined and cultured persons whose ideas were widely circulated. They were well known for their good observation of the proprieties."
