《资治通鉴·汉纪·汉纪二十二》
大的诸侯国食邑不过数县，由朝廷委派的官吏控制那里的权柄，使诸侯王不能有所作为，不会形成当年吴、楚、燕、梁等诸侯国尾大不掉的局势。
诸侯大者乃食数县，汉吏制其权柄，不得有为，无吴、楚、燕、梁之势。
Large fiefdoms only had jurisdiction over a few counties and the officials appointed by the court controlled all powers there, so the vassal kings could not accomplish anything. This would not lead to the situation that occurred back when the states of Wu, Chu, Yan, and Liang became so powerful that they could not be controlled.
