送子由使契丹 苏轼

云海相望寄此身，哪因远适更沾巾。 不辞驿骑凌风雪，要使天骄识凤麟。 沙漠回看清禁月，湖山应梦武林春。 单于若问君家世，莫道中朝第一人。

Sending Ziyou to Khitan (literal translation)

I am sending this body to the sea of clouds, why should I weep because of the long journey. I ride the post without hesitation and brave the wind and snow, to let the proud people know the phoenix and unicorn. Looking back at the clear moon in the desert, the lake and mountains should dream of the spring in Wulin. If the Chanyu asks about your family background, don't say you are the best in the Central Dynasty.
