《资治通鉴·唐纪·唐纪三》
王世充在太尉府的门外树立三个牌子：一个牌子招求有文学才识、足能成就时务的人；一个牌子招求有武勇智略、能带头摧锋陷敌的人；一个牌子招求遭受到冤屈、郁郁不得申说的人。
世充立三牌于府门外，一求文学才识堪济时务者，一求武勇智略能摧锋陷敌者，一求身有冤滞拥抑不申者。
Wang Shichong erected three signboards outside the Grand Tutor's office. One sign sought people with literary talent and knowledge, capable of accomplishing the state affairs of the time. One sign sought people with military courage and resourcefulness, and able to take the lead in humbling and destroying the enemy. One sign sought people who had suffered injustice and were deeply depressed and not able to speak out.
