Zang Wenzhong (藏文仲) is the posthumous title of Zang Sunchen, a minister of the state of Lu who lived during the 7th Century BC and was apparently regarded by his contemporaries as a man of wisdom.
Confucius clearly didn’t share that opinion of him. In Chapter XVIII of Book 5, he reproaches him (depending on which interpretation you find more credible) for his impertinence in usurping royal privilege by keeping tortoises in elaborate accommodation, or for adding beautiful decorations in order to inspire the spirits to give out a favorable reading when the shells of the poor beasts were smashed apart for the purpose of divination.
If that weren’t sufficient, he goes on to lambast him in Chapter XIV of Book 15 for stealing the position a fellow minister called Liuxia Hui (柳下惠) even though he knew had great ability.
Confucius said: “Zang Wenzhong kept a tortoise in a house featuring pillars patterned with mountains and posts above the rafters decorated with duckweed motifs. What does this say of his wisdom?”
Confucius said: “Zang Wenzhong stole his position! He knew that Liuxia Hui had great ability but wouldn’t share the position with him.”
