《北史·列传·卷八》
可是王建认为慕容宝这次失败，国内已经空虚，这些人被俘虏了却又放回去，这是放走敌人再生后患，不如杀掉。
建以为宝覆败于此，国内空虚，获而归之，纵敌生患，不如杀之。
However, Wang Jian believed that Murong Bao's failure this time meant that his country was already empty, and that if these people were captured and then released, it would be like releasing the enemy to cause trouble later, so it would be better to kill them.
