《后汉书·列传·章帝八王列传》
受恩赐大国，我的职责是做朝廷的屏藩辅佐，新近就要离开京师，孤独一人，忧心如焚。日夜惶恐，不晓得怎么自处。
蒙恩大国，职惟籓辅，新去京师，忧心茕茕，夙夜屏营，未知所立。
I have been granted a great fiefdom, and it is my duty to be a bulwark and an aide to the court. Now that I am about to leave the capital and become a lonely person, I am filled with anxiety. I am in constant fear and trepidation, and I do not know what to do with myself."
