《三国志·魏书·崔毛徐何邢鲍司马传》
崔琰曾经举荐钜鹿人杨训，认为他虽然才能不够，大清廉忠贞，坚守道义，太祖立刻按理解征召他。
琰尝荐钜鹿杨训，虽才好不足，而清贞守道，太祖即礼辟之。
Cui Yan once recommended Yang Xun from Julu, believing that although he was not talented enough, he was clean, loyal and steadfast in upholding righteousness. Taizu immediately summoned him as he understood.
