《北史·本记·卷十二》
周称多士，汉号得人，上想前风，满怀钦伫文武官员在职任事者，五品以上的，应依令十科举人，有一艺可取便可举荐，不必求全责备。
以此求理，庶几非远。文武有职事者，五品已上，宜依令十科举人。有一于此，不必求备。
In the Zhou dynasty, there were many scholars, and in the Han dynasty, many talented people were appointed. Thinking back to the past, I am filled with expectation that the civil and military officials who are now in office, of the fifth rank and above, should, in accordance with the order, recommend ten candidates. If they have one skill, it will be enough to recommend them, and it is not necessary to seek perfection.
