《汉书·表·诸侯王表》
虽然称号和王位在天下之内失去，仍有枝叶维持似的，无人敢占据空虚的王位，海内没有天子，有三十余年。
号位已绝于天下，尚犹枝叶相持，莫得居其虚位，海内无主，三十余年。
Although the title and throne were lost in the world, there were still branches and leaves to maintain it. Nobody dared to occupy the vacant throne, and there was no emperor in the world for over thirty years.
