Synopsis of the story of "The Unsolved Formula of Wutong Lane"
When he was nine years old, Xia Wang traveled to New York with his sister Xia Wanxing due to the death of his parents. Only the silver key pendant left by his grandmother and the plane tree in the backyard became the last warm anchors in his memory. When his grandmother passed away when he was twelve years old, he returned to his hometown with his sister and transferred to Mingcheng Middle School with the pen and red string that carried his childhood.
On the day he transferred to another school, Xia Wang confessed under the pen name "Summer Wutong", which unexpectedly aroused heated discussion - his "Wutong Alley" series, full of cicada chirping and frosting, has long become the collective memory of his student days. Su Mu, the stern class monitor who always hides mathematical poems in his textbooks and wears silver-rimmed glasses, not only has a similar curvy hair to him, but also handed over a sticky note filled with metaphors when they met: ∑ (area of the sycamore leaf) = the wind stirred up when you passed by.
In campus life, Xia Wang found a home at the intersection of literature and mathematics: in class, he used a pen to write sonnets on the edge of the draft paper, and Su Mu responded with calculus symbols; during recess, the girls held up "Wutong Lane" to ask for signatures, and the boys made fun of the "Bingshan Monitor" for his unusual gentleness. The red ropes that complement each other on their wrists, the corresponding scars on their collarbones, the similar sycamore leaf tattoo on the back of their neck, and the blue umbrella bookmark with the word "wang" engraved on it between the pages of Su Mu's book, quietly weave a secret connection spanning seven years.
The companionship of his sister Xia Wanxing and her brother-in-law became the pillars of Xia Wang's reorganization of his life. The "Gears and Monsoon" comic given by his brother-in-law, the sycamore tree in the backyard that needs regular watering, and the daily disputes over tying a tie in front of the entrance mirror all collage the shape of "home" out of trivial matters. However, when the blue umbrella Xia Wang picked up in front of the ruins, the umbrella bookmark found in the Sumu antique market, and the "destined person" mentioned by his grandma before her death gradually overlapped, the summer of sixteen years old finally opened the prologue in the monsoon: two souls marked by sycamore leaves, looking for each other's coordinate system in the gaps between lines of poetry and formulas.
Concept: ∑ (Pinca sycamore leaf area) = the wind you stir up when you pass by.
