The Universal Material of Argumentative Writing: Ding Zhen
At the end of last year, Li suddenly became angry; At the end of this year, Ding Zhen suddenly became angry.
Ding Zhen and Li are actually a little similar. Although they are popular and have high-value factors, more importantly, we see a kind of cultural nostalgia in them.
Especially Ding Zhen, those innocent eyes remind us of childhood and childhood dreams.
Just like one of Haizi's most famous poems, we all dream of "being a happy person from tomorrow", "feeding horses, chopping wood and traveling around the world" and "I have a house facing the sea, with blooming spring flowers".
Nowadays, as "996" workers in the city, we are exhausted by high housing prices and children's extracurricular classes. Holderlin said, "People live poetically", but where can we find a poetic dwelling place? Jack Ma, the richest man, said, "996" is still your blessing!
The word "homesickness" is particularly rich in connotation. What are we worried about? Is the hometown unable to go back? No, my hometown is still there, and the high-speed train can go back in a few hours.
Although the hometown in reality can go back, this hometown that can go back does not seem to be the hometown in our memory. The hometown in my impression is so hazy, so warm and so sweet; This hometown will always be in our memory, and in our dreams, we can never go back.
Among Lu Xun's novels, my two favorite ones are Hometown and Social Drama. Some of his novels, such as Kong Yiji and Sister Xianglin, are certainly good, but the characters in them are far away from the present life. And "Hometown" and "Social Drama" still feel very cordial today, because that cultural homesickness will be hidden in the hearts of every generation.
I don't know how popular Zhen will be. No matter how the years pass, there will always be a real Ding in our hearts.
