Du Di 'er in the story of walking through the wall is a nobody and a very quiet person. He has "amazing energy" to walk through walls without blowing dust, but he didn't want to show it at first, let alone have any benefits, and regarded it as a disease. It was not until the new boss criticized him for being picky and sent him to a dark room full of sundries, viciously insulting his personality and dignity that he realized that this was a means of revenge. He hid the body in the wall with his head "hanging on the wall" and "like the head of a hunted animal". He appeared in the boss's office more than twenty times a day, denouncing and threatening the boss until the man was taken to a nursing home by an ambulance. In his Free Travel and Revenge on the Wall, Dutil got real human extension and the pleasure of life. And this kind of "stretching" and "pleasure" finally activated the desire and fantasy of the dormant person in him. If revenge is just his passive resistance to human nature, then robbing banks, stealing jewelry stores and teasing the warden are active challenges to the existing order. He wants to win the respect of society and satisfy his desire for freedom. He succeeded, he got the "reverence" he longed for, and even got the favor of a blonde, and she had a spring breeze overnight. But he finally failed, and he was embedded in the stone wall forever. The previous "great joy" was intended to set off the "great sorrow" at this time. The "deep voice from the grave" seems to pour out his bitterness, and it seems to express the deep sigh that human beings must endure all kinds of constraints and cannot be freed.
This paper is similar in conception to Pu Songling's The Taoist of Laoshan Mountain, but the Taoist of Laoshan Mountain expresses the moral concept of "being honest and clean, or not testing", while Aimei expresses all kinds of obstacles and inhibition of "wall" on human nature in the real social state through a little person's rhapsody. This "wall" used to be a barrier to protect Doutie's personality, but it is actually his eternal grave.
