《汉书·传·赵尹韩张两王传》
在此以前，趟广汉做太守，忧虑当地风俗喜聚朋结党，因此交结官吏和百姓，使他们互相告发，这种权宜之计是为了明察政事，颖川因此告发成风，百姓多结仇成怨。
先是，赵广汉为太守，患其俗多朋党，故构会吏民，令相告讦，一切以为聪明，颍川由是以为俗，民多怨仇。
Guang Han was the governor before this, worried about the local custom of gathering and forming parties, so he made friends with officials and people, and asked them to report to each other. This expedient measure was to understand political affairs. Yingchuan therefore reported and the people became more enmity.
