《宋书·列传·卷五十九》
孝伯又说： 张长史，我是中州人，长期住在北国，与汉族风俗相隔，两国交兵不能充分表达我的情义，身边都是监视我的人，你应该真正理解我。 
孝伯又曰： 长史，我是中州人，久处北国，自隔华风，相去步武，不得致尽，边皆是北人听我语者，长史当深得我。 
Xiaobo then said: Zhang Zhangshi, I am from the Central States but have long lived in the northern lands, and the customs of our ethnicities are different. When the two countries go to war, I cannot fully express my feelings, and all the people around me are monitoring me. You should truly understand me.
