《汉书·传·贾谊传》
诸侯王国的力量强大丫，必然会造成与朝廷互相猜疑对立的局势，民众因此屡次遭受灾祸，朝廷也常为此而忧虑，这实在不是安定朝廷、保全民众的办法。
夫树国固必相疑之势，下数被其殃，上数爽其忧，甚非所以安上而全下也。
The power of feudal kingdoms is strong, which will inevitably lead to a situation of mutual suspicion and confrontation with the imperial court. As a result, the people have suffered disasters repeatedly, and the imperial court is often worried about it. This is really not a way to stabilize the imperial court and protect the people.
