Book 3: 《八佾》 Ba Yi (Eight Rows)
《八佾》 Passage 3.22
子曰：「管仲之器小哉！」或曰：「管仲儉乎？」曰：「管氏有三歸，官事不攝，焉得儉？」「然則管仲知禮乎？」曰：「邦君樹塞門，管氏亦樹塞門；邦君為兩君之好，有反坫，管氏亦有反坫。管氏而知禮，孰不知禮？」
Legge Translation (1861)
The Master said: "Small indeed was the capacity of Guan Zhong!"Some one said: "Was Guan Zhong parsimonious?"
"Guan," was the reply, "had the San Gui, and his officers performed no double duties; how can he be considered parsimonious?"
"Then, did Guan Zhong know the rules of propriety?"
The Master said: "The princes of States have a screen intercepting the view at their gates. Guan had likewise a screen at his gate. The princes of States on any friendly meeting between two of them, had a stand on which to place their inverted cups. Guan had also such a stand. If Guan knew the rules of propriety, who does not know them?"
