The reason Toegye Lee Hwang and Yulgok took the exam and served as government posts in the past.

 Toegye Lee Hwang, who is the same age as Nammyeong, hoped that it would be a silver day that devoted himself only to learning, but studied liberal arts and lived as a government official. What's the reason? Toegye was not a family that could be called within that era. My parents' house was in a position to be dismissed because they had a lower status than my wife's house. He took the liberal arts course to raise the family and please his single mother.』 - Nammyeong and Toegye have not met each other in their lifetime, but they were not branch offices where they exchanged letters. Nevertheless, Nam Myung was only critical of Toegye's source, but why did he do that? Toegye asked his disciples to write Toe Do-man on his scream (Eun-il, who stepped down late to bankruptcy), and Nam Myung-eun, who heard the news, once questioned how a liberal arts graduate could write Man. Why would Toegye want to hold a government post in a dizzy court? So Toegye tried to return to Dosan by turning his head around whenever there was an opportunity. 』 -Yulgok Yi I was famous as Gudojangwon (9 times in the past). His past test answer, Cheondo Book, is surprising how he was able to write so logical in such a short time even now. Yulgok also went through the past to rise his status. But at that time, Sarim laughed at him, saying, "I'm obsessed with taking tests." Yulgok's friend Seong-hon (son of holy water) sends a letter saying, "You and I are friends, and I are ashamed to see others." Yulgok said, "Don't say things you don't know." Who recognizes my family? "You are well-off because you have a good ancestor, but I can't live without a government post."』  Among the monthly in-depth interviews of Professor Kim Chung-ryul of the Oriental Philosophy circle, Toegye, a one-line summary of the Joseon Dynasty, and Yulgok's family had little to do, making it difficult to make ends meet. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Some male students who have not completed military service can take the exam for practical military service purposes (to make it easier), but the first reason they take the exam is because they are hungry and have similar facts to the military burden at the time. <...The Toegyejeonseo contains the following. Toegye Lee Hwang is in charge of management in Seoul and sends a letter to his son in Seoul. Sooner or later, a military temple will enter Toegye's hometown, so it is recommended that the temple be caught and not covered by military service targets. In other words, in principle, even a nobleman had to serve in the military. However, former and incumbent officials and Confucian students from local Confucian schools were exempted. There is a fixed amount for each region and a list, so it was managed quite systematically.>
