《晋书·志·第十章》
衹有双亲生离，吉凶不知，如果服丧凶讯又不确实，从吉又怕父亲已去世，心中忧虑而服素服，这是出于人情，如有这样的情况，就不是国家的制度所能裁断的。
唯二亲生离，吉凶未分，服丧则凶事未据，从吉则疑于不存，心忧居素，出自人情，有如此者，非官制之所裁。
Only when parents are separated from each other, and do not know whether they are alive or dead, if they mourn for the dead news but it is not confirmed, they are afraid that their father has passed away, they are worried and wear mourning clothes. This is out of human nature. If this is the case, it is not something that can be judged by the national system.
