《北史·列传·卷四十二》
小时候他们参加围猎，父亲斛律金命子孙们聚集一起看他们射箭，然而却流着眼泪说： 明月、丰乐使用弓箭赶不上我，孙子们又赶不上明月和丰乐，真是一代不如一代啊。 
少时猎，父金命子孙会射而观之，泣曰： 明月、丰乐用弓不及我，诸孙又不及明月、丰乐，世衰矣。 
When they were young, they attended a hunting expedition, and their father Houchulu Jin ordered his descendants to gather and watch them shoot arrows. However, he shed tears and said, "Mingyue and Fengle's archery are not as good as mine, and the grandchildren are not as good as Mingyue and Fengle. It is truly each generation is worse than the previous one."
