In the Course of weaken Royal power weakened at the late of Chosun Dynasty, The Shilhak-Scholars criticized the abnormal strengthening of vassal power, and claimed the reform of the State Council(議政府) and Six Ministries(六曹)system. They, however, insisted that the king should not monopolized official affairs with the vigorous sovereign power. Furthermore, they objected that eunuches who stood by king side intervened in state affairs. In this respect, it seems to me that both of bureaucrat's opinion and Shilhak-Scholar's opinion was similar to each other. That is, the both of them thought unsatisfactorily that eunuches set up Naesibu(內待府) and then had an independent government office. They, therefore, asserted the reduction of Naesibu(內待府)'s organization or its abolition. Politically they demanded varied measures in order to prohibit from eunuches taking part in state affairs in advance. They also maintain the ban on the eunuch's court official promotion, the limitation of their relays of the king's orders, the restriction of their official rank, the marriage prohibition, the dress classification, and so forth. They insisted that eunuches should not take part in the conducts of state affairs, and thought that it was a mistaken political course to relay the king' s order by eunuches itself. These arguments identified the bureaucrat's awareness of eunuch and the "Nee-Confucian literati"(士林)'s at the early of Chosun Dynasty with the bureaucrat's and the Shilhak-Scholar's at the late of Chosun Dynasty.
