《汉书·传·王贡两龚鲍传》
龚胜为郡吏，三次被举为孝廉，但因为是王国的人，不能担任宫中宿卫。后补为吏，两次任为尉，一次任为丞，每次龚胜都是到任不久就辞官而去。
而胜为郡吏，三举孝廉，以王国人不得宿卫补吏，再为尉，一为丞，胜辄至官乃去。
Gong Sheng served as a county official and was recommended for filial piety and integrity on three occasions, but because he was from a vassal state, he could not serve as a palace guard. Later, he became a minor official and served twice as lieutenant and once as deputy minister. Each time, Gong Sheng resigned shortly after taking office.
