《资治通鉴·梁纪·梁纪六》
当时，东夏州全境俱反，到处贼寇聚集，源子雍转战而前，九十天之内，经历了几十场战役，终于平定了东夏州，于是征收税粟送往统万城，夏州、东夏州因此而得到保全。
时东夏州阖境皆反，所在屯结，子雍转斗而前，九旬之中，凡数十战，遂平东夏州，征税粟以馈统万，二夏由是获全。
At that time, the Dongxia Prefecture was in rebellion, and there were bandits everywhere. Yuan Ziyong went into battle, and within 90 days, through dozens of battle, he finally put down the rebellion in Dongxia Prefecture. Then he collected taxes to Wucheng. Xia Prefecture and Dongxia Prefecture thus were preserved.
