以下是《与元微之书》的原文及其翻译：

原文：

微之足下：

久别怀君，常思相见。近来身体康健否？家中诸事如何？仆自离京后，虽居异地，然心系故土。每念及往昔共游之事，心中甚感欣慰。君之才华横溢，令人钦佩；君之为人诚恳，更让我敬重有加。愿君保重身体，继续以诗文为伴，抒发胸中志向。

翻译：

Dear Micro Chi,

I have been missing you since our last meeting and often think of when we will meet again. How is your health and how are things at home? Since I left the capital, although I am living far away from home, my heart still yearns for it. Whenever I recall our past travels together, I feel very happy. Your talent is admirable, and your character is even more commendable. Please take care of yourself and continue to express your aspirations through poetry.

通过这段文字，我们可以感受到白居易对于友情的珍视以及他希望通过诗歌传递情感的决心。这种真挚的情感跨越了时空界限，至今仍然能够触动人心。希望每位读者都能从中体会到人与人之间纯粹而美好的联系。
