《旧唐书·列传·卷四十二》
唐设六科取士，其中以经义录取的谓之明经。韦安石考明经科而中举，连续授乾封县尉。苏良嗣很看重他，以礼相待。
安石应明经举，累授乾封尉，苏良嗣甚礼之。
Tang set up six categories of imperial examinations, with those selected based on knowledge of canonical texts being called “Mingjing” (understanding classics). Wei Anshi passed the Mingjing exam, and was successively awarded the position of the lieutenant of Qianfeng County. Su Liangsi regarded him highly, and treated him with respect.
