Here is the exhaustive biography of Sima Hui (司馬徽 / 司马徽), courtesy name Decao (德操), sobriquet Water Mirror / Shuijing (水鏡) (? – 208), a celebrated hermit and judge of talent in Jing Province, incorporating historical records and the narrative of Romance of the Three Kingdoms.
Contents
Historical Career
Sima Hui was a native of Yangzhai, Yingchuan Commandery (Yu Province). He lived as a reclusive scholar in northern Jing Province and was renowned for his clear-sighted evaluation of character. His friend Pang Degong (uncle of Pang Tong) bestowed on him the famous sobriquet “Water Mirror.” Historically it was Pang Degong who first described Zhuge Liang as “Sleeping Dragon” and Pang Tong as “Fledgling Phoenix,” while calling Sima Hui “Water Mirror”; Sima Hui later repeated the recommendations to Liu Bei.
He was known for answering nearly every question with the non-committal phrase “Good, good” (好, 好), a habit his wife joked was ingrained in his speech and which is widely interpreted as a deliberate means of avoiding political entanglement. After Liu Cong surrendered Jing Province to Cao Cao (208), Cao Cao sought to employ Sima Hui, but the hermit died of illness before he could be put to use. Among those associated with him as students or protégés were Xiang Lang, Liu Yi, Yin Mo and Li Zhuan; popular tradition also links him with Xu Shu, Zhuge Liang and Pang Tong as teacher or mentor.
Romance of the Three Kingdoms Portrayal
In the novel Sima Hui appears as the wizened “Master Water Mirror.” He first meets Liu Bei in Chapter 35 after the latter’s escape from Cai Mao’s assassination attempt (the famous leap of Dilu across the Tan Stream). A young servant guides Liu Bei to the hermit’s hut; Water Mirror has already foreseen the events. After hearing Liu Bei’s story he advises him to seek a worthy strategist and utters the celebrated line: “If you could find either Sleeping Dragon or Young Phoenix, you could restore order in the empire.” He refuses to give clearer identification and answers further questions only with “Good, good!”
In the following chapters Xu Shu (who had been scolded by his master) hurries to Liu Bei’s side. When Water Mirror later learns that Xu Shu has been tricked into leaving for Cao Cao, he is disappointed; upon hearing that Zhuge Liang has been recommended as the Sleeping Dragon he relates stories of Zhuge’s talent, comparing him to Lü Wang and Zhang Liang, then departs. The novel thus makes Sima Hui the pivotal figure who points Liu Bei toward the two great advisers of Shu.

Historical Note
Historically Sima Hui was a reclusive scholar of Yingchuan origin living in Jing Province, celebrated for his ability to judge character. The famous sobriquets “Sleeping Dragon,” “Fledgling Phoenix” and “Water Mirror” were originally coined by Pang Degong; Sima Hui repeated the recommendations of Zhuge Liang and Pang Tong to Liu Bei. He died in 208 before Cao Cao could make use of him. The novel expands his role into the dramatic “Master Water Mirror” episode that directly sets Liu Bei on the path to obtaining Zhuge Liang, thereby giving him a pivotal place in the founding mythology of Shu Han.
