《陈书·本纪·卷三》
凡是前代王侯，古来忠烈，坟墓被毁而没有后代的，可检视修理，墓地的树木，不能砍伐，这样才使幽魂安适，使我满意了。 
维前代王侯，自古忠烈，坟冢被发绝无后者，可检行修治，墓中树木，勿得樵采，庶幽显咸畅，称朕意焉。 
All the tombs of the former kings and vassals, and the loyal and brave men of ancient times, which were destroyed and had no descendants, should be inspected and repaired, and the trees in the cemetery should not be cut down, so that the ghosts could feel at ease, and I would be satisfied.
