How to understand Kong Yiji's "not being recognized by others and becoming a laughing stock in others' eyes"?

Young people don't understand Kong Yiji, and reading is already a book. Kong Yiji is the hero in Lu Xun's novel Kong Yiji. He has read a lot of books, always speaks differently, and behaves gently and generously. He is a typical literati image, but he has never won a place in the imperial examination, let alone become a senior official. Kong Yiji is a good wine. With a few dollars, he went back to the restaurant to drink a bowl of wine and eat a bowl of fennel beans. He is also generous and willing to share fennel with children who have laughed at him. He is acting strangely. When drinking, he always wears a long coat and doesn't sit on a stool to drink. All kinds of behaviors seem to be out of tune with the people around him. As an educated man, his life is not better than others, but poor, so he is ridiculed and becomes a verbal joke of frequent customers in restaurants.

1, a lofty scholar whose words and deeds are consistent. Although Kong Yiji is down and out, he doesn't want to think of himself as a person inferior to other drinkers. He dresses differently from others, drinks differently from others, and often writes different famous sentences. However, this difference is a scholar's integrity, but it is an unsociable joke in the eyes of the world.

2. Kong Yiji is full of ambition, but never does anything. Life is made by hands, not by mouth and mind, but Kong Yiji has a rich heart and a rich mouth, but he is a complete dwarf in action. Among the working people, everyone wears short sleeves and supports themselves with both hands, but even if Kong Yiji is down and out, he always wears a long gown and looks unpaid.

3, Kong Yiji read the holy book, and commit theft. What Kong Yiji stole was not clothes or money, but the book he didn't lack most. In the second half of the novel, it is explained that Kong Yiji has disappeared from the eyes of the world for a long time because his leg was broken because he stole Ding Gu's book. This also pushed Kong Yiji's image to a climax, implying his tragic fate. Even when he died, he was regarded as a joke by the living people, and they were asked to point at him after dinner as a boring topic.
