What do you get from the story written in the article Kite?

Taking the kite as a guide, I deeply reflect on the words and deeds of "I" who treated my brother rudely. Through this little "I", we can see how sacred, cruel and ignorant the whole social appearance under the old ethics-the big "I"-paternalistic management and pecking order are, which stifles children's nature. When the author digs into the social causes of the tragedy, the memory of "I" is an accusation against the children devastated by the feudal clan system, which has profound ideological significance. "I" feel extremely heavy after deeply reflecting on the irreparable fault of this place. This sense of repentance negates the old "I" and gives birth to a new "I". The ideological evolution of "I" is clear, and the complex psychological state of "I" shows that it is for these reasons that I feel "surprised and sad" when I see a kite in the sky in Beijing.
