Choe Chiwon
According to the 12th century history work "Samguk Sagi", when Choe was twelve years of age, in 869, his father sent him to study in Tang, seeing him off with the admonition that if he did not pass the Chinese imperial examination within ten years he would cease to be his son. Within the decade Choe did indeed pass the highest of China's civil service exams, the coveted "jinshi" (進士) degree, and was duly appointed to a prefectural office in the south. Choe went on to serve in China for nearly a decade, even becoming intimate with Emperor Xizong of Tang (r. 873-888). Choe also won merits for his service under the Tang general Gao Pian in his struggle against the Huang Chao rebellion, a failed uprising which nonetheless ushered in the final years of the crippled Chinese dynasty. With the rebellion put down and peace at least temporarily restored Choe's thoughts turned towards home. One surviving poem, written earlier while Choe was heading to his first official post in China ("ten years of dust" being his ten years spent in preparing for the exam), gave vent to his emotions regarding the native land and family he had not seen in a decade:
The "Samguk Sagi" again tells us that Choe - the consummate Confucian - was thinking of his ageing parents when he requested permission from the Tang emperor to return to Silla. This he was duly granted and he returned home in 885. He was then 28.
