"How is the Goldbach conjecture?"
"Ready soon."
"Uncle, are you cold?" Pipi asked.
"It's not cold." The old man smiled and rolled his trousers. The lining of his trousers was tightly insulated with a plastic bag and stuck on with a circle of stickers. "It's very warm. Can you lend an old man a few dollars, Pipi?"
"Here's fifty. You don't have to pay it back." Pipi pulled out her wallet and handed him a banknote.
"Thank you," the old man took the money and took a stack of papers from his own bag and handed it over. "This is my manuscript. I have received the Fields Prize. You can take this for the money."
Pipi took it with both hands, showing her respect: "Okay, I will look after it."
Who says that adults are more down-to-earth than children?
That dirty old man was Xin Xiaoqiang, the father of Xin Xiaoju.
He had been a salesperson at Xinhua Bookstore more than a decade ago and had never been to college. Because he saw Mr. Xu Chi's "Goldbach Conjecture", he decided to devote his life to the cause of the Goldbach conjecture. He tried to prove it for five years, but he could not prove it, and in the end his wife left him. He tried for another five years, but eventually he just ended up in a mental hospital. After leaving the hospital, he began to wander, sleep on the streets, and occasionally going home to put pencil to paper and see his daughter, never abandoning his dream.
Xiaoju had always admired her father, always thinking that he was a genius mathematician, until one day she took the courage to take his father's manuscript to visit a provincial mathematics authority. After reading it carefully, the authority told her very seriously: "Your father is a genius, but he does not understand mathematics."
The world of Xiaoju fell apart.
She had been the top at math in her class, but she behaved strangely and liked to argue. The teachers didn't like her. Raising her hand would usually just get her ignored..
In addition, her temper was very explosive, and she loved to fight. She was too loyal, a trait which often got her taken advantage of.
The biggest thing was that she lived close to the crematorium and the tomb of the martyrs, so everyone thought she was unlucky.
