《宋史·本纪·卷二十六》
从今以后没有担任县令的不能授给监司、郎官，没有经历外任的不能授给侍从官，成为法令。
自今不历县令者勿除监司、郎官，不历外任者勿除侍从，著为令。
From now on, those who have not served as county magistrates will not be granted the position of supervisory officer or official, and those who have not served in foreign posts will not be granted the position of attendant, and this will become law.
