《荀子·宥坐》
孔子说： 太庙的北堂当然是有讲究的，官吏们招来技艺精良的工匠，依据木材来施加文采，这并非没有好的大木头，恐怕是由于看重文采的缘故吧。 
孔子曰： 太庙之堂亦尝有说，官致良工，因丽节文，非无良材也，盖曰贵文也。 
Confucius said: "Of course, there is a reason for the North Hall of the Ancestral Temple. Officials recruited skilled craftsmen to apply decoration to the wood based on the wood. It's not that there was no good timber, but it was probably due to the emphasis on decoration."
