What are the image descriptions of Mr. Wen Yiduo in Selected Works? Tell me about their functions.

There are many specific descriptions of Wen Yiduo's language and portrait in this paper. For example:

(1) Language description: For example, "I will do what others say." "People don't necessarily do what they say, and I don't necessarily say what I do." These two sentences show Wen Yiduo's pragmatic spirit and modest attitude as an outstanding scholar. Another example is: "We should be prepared to step out of the gate with the front foot like Mr. Li, and don't step into the gate with the back foot." Show Wen Yiduo's fearless revolutionary spirit.

(2) Portrait description: such as "bright eyes", "messy hair", "hold your head high", "long beard fluttering" and "seeing the garden" all show Wen Yiduo's respectable tall image.

(3) Description of details: For example, "One bamboo notebook after another is densely covered with fine print, like swarms of ants", which shows Mr. Wen Yiduo's rigorous academic spirit.
