“尺幅千里”,意指在一尺方的画幅里,能反映出极广阔的内容。对于这种艺术概括力,闻一多作过非常通俗的解释,有一次上课,他在黑板上写了“2+5=?”学生先是哄堂大笑,接着迷惑不解:老师怎么把这么简单的算术题拿到课堂上来?但闻一多坚持问:“2+5=?”学生只好回答:“等于7嘛!”闻一多说:“不错,数学上2+5=7,这是天经地义、颠扑不破的,但是在艺术领域里,2+5=1000,甚至等于10000也是可能的。” “Several miles” means that one-foot square footage can reflect extremely broad contents. For this kind of artistic summarization, Wen Yiduo made a very popular explanation. There was a class. He wrote “2+5=?” on the blackboard. The students laughed first and then confused: how did the teacher make it so simple? Did you get the maths question in the class? But as soon as you heard the question, “2+5=?” ​​The student had to answer: “It’s equal to 7!” Wen Yiduo said: "Yes, mathematically 2+5=7, this is Naturally correct, irrefutable, but in the field of art, 2+5=1000, even equal to 10,000 is also possible.”
