《史记·七十列传·李斯列传》
齐国人淳于越劝谏道： 我听说殷商和周朝统治达一千多年，他们分封宗室子弟和功臣，作为自己的辅翼力量。
齐人淳于越进谏曰： 臣闻之，殷周之王千馀岁，封子弟功臣自为支辅。
Chunyu Yue from Qi advised: I have heard that the Shang and Zhou dynasties ruled for more than a thousand years, they enfeoffed their royal relatives and meritorious subjects as vassals, to be their wings and arms.
