7) "Seeing Beyond the Picture" This paragraph talks about the profundity of creative thinking, that is, creative thinking can see the essence through phenomena. The passage begins with an account of a farmer in Iowa who sees a new railroad and thinks only of rails and trains. Then through the argument, it was pointed out that the railway would not only mean rails and trains, but also bring profound changes to the lives of the locals, which the farmer did not see.

Through this example, the author pointed out that the creator should be good at seeing the development of things, the result of the development of things, that is, thinking further through the surface of the "picture" and seeing the essence through the phenomenon. People with creative thinking are good at seeing the deeper things behind the "picture" according to the connections between things, either layer by layer, or horizontally. This way of thinking of "going deeper layer by layer" and "opening up horizontally", that is, creative thinking, is characterized by profundity and expansiveness, which Oher vividly calls "seeing beyond the picture".
