《世说新语·文学》
支道林听到后，说； 对圣贤，自然不用说了，从中等才质以下的人来说，北方人读书，像是在敞亮处看月亮；南方人做学问，像是从窗户里看太阳。 
支道林闻之曰： 圣贤固所忘言。自中人以还，北人看书，如显处视月；南人学问，如牖中窥日。 
When Zhi Daolin heard this, he said: For the saints, of course, it goes without saying that, for people of moderate talent and below, northerners who read are like watching the moon from a bright place; southerners who study are like watching the sun from a window.
