《周礼·秋官司寇·士师&朝士》
按四季贯彻施行县法，到了夏历年终就检查县法的执行情况，而对采邑的官吏进行奖惩。凡都士、家士所上报的有疑难的案件，就负责初审而后上报大司寇。
若岁终，则省之而诛赏焉，凡都家之士所上治，则主之。
The county law was consistently implemented throughout the four seasons. At the end of the Chinese year, the implementation of the county law was reviewed and the officials of the feudal domains were rewarded or punished. The Dutou and Jiazhou reported any doubtful cases, and were responsible for the preliminary hearing before reporting them to the Grand Minister of Justice.
