"You are from Yuanmou, Yunnan, and I am from Zhoukou, Beijing." Where does this poem come from?

The essay "One Hundred Years of Solitude" is selected from the collection of modern Cen Mengbang's personal works "If there is no sun tomorrow". The original fragment is:

Before that, I have been analyzing the evolutionary dynamics of human beings. I once came to an absurd conclusion that human beings walk upright to prevent sciatica, which was later overturned by myself. I began to believe that it is because women go first and men have to walk upright in order to kiss, so in the final analysis, the driving force of evolution should be love. ?

Therefore, my attitude towards love is almost religious, and I wrote a poem specially for this purpose: Primitive Love. You are from Yuanmou, Yunnan, and I am from Zhoukou, Beijing. I took your hairy hand and took a gentle bite. Love makes us walk upright!

It is said that this poem is the first of symbolism and has become one of the rare classics in the history of China's poetry. But the pessimism brought by lovelorn gave me a spiritual shock, and I began to doubt my beliefs. This dilemma makes me extremely annoyed.

Extended data:

In the essay One Hundred Years of Solitude, music, movies, writing, dreams, reading, friendship and love are all related to one's daily life and preferences. Fragmented fragments of life and youthful gibberish of different lengths reveal the author's true feelings and sentiments about life. In One Hundred Years of Solitude, Cen Mengbang also tends to express his inner world and delicate feelings in adolescence.

Because of the relatively limited life experience and life experience, Cen Mengbang's "small feelings" are generally manifested in his personal life experience and inner feelings. This is quite different from Lin Bai's "body writing" and the desire appeal of "new generation" writers.
