《三国志·魏书·诸夏侯曹传》
而中正官只需要考察官员的日常行为，分出高下，再评定官员所属的等级，不要出现不合理的升职降级。
中正则唯考其行迹，别其高下，审定辈类，勿使升降。
The Chinese government officials only need to examine the daily behavior of the officials, differentiate between the high and the low, and then evaluate the level of the officials. There should be no unreasonable promotion or demotion.
