《北史·列传·卷二十八》
如果有空缺的官职却因为这个人去守孝，无人能替补，则可以用特殊的诏书对他慰勉，让他回来继续任职。
若无其人有旷官者，则优旨慰喻，起令视事。
If there is an official position vacancy and it is not possible to have it filled due to the person being in mourning and there is nobody to appoint in their stead, they should be comforted with a special imperial decree and be directed to return to continue their duties.
