《三国志·吴书·刘繇太史慈士燮传》
太史慈就到了平原，对刘备说： 我孔慈，是东莱的见识浅薄的人，和孔北海并非骨肉至亲，也不是同乡旧友，只是因为名声志向相似而交好，有忧患与共的情义。
遂到平原，说备曰： 慈，东莱之鄙人也，与孔北海亲非骨肉，比非乡党，特以名志相好，有分灾共患之义。
Tai Shici arrived in Pingyuan and said to Liu Bei: I, Kong Ci, am a shallow person from Donglai, and Kong Beihai is not my blood relative or old friend, but we became friends because our reputations and ambitions were similar, and we shared a camaraderie that meant we would face adversity together.
