After Liu Lu, a junior, solved the mathematical puzzle of Sitapan conjecture, Central South University also selected talents in an eclectic way, and hired Liu Lu, who was only 23 years old, as a full professor researcher. Liu Lu became the youngest professor in China. It's a good story for a while.

"Math fanatic" Liu Lu said that genius is always different, but for Liu Lu, he never felt different from others. Perhaps the only difference is his special attention to mathematics.

He has been particularly fond of mathematics since he was a child. When his classmates are scratching their heads for mathematics, he can always have fun in the boring world of mathematics and learn with relish. In 2008, Liu Lu was admitted to the university, and originally wanted to choose his favorite math major. But his parents thought that if he majored in pure mathematics, it would be difficult to find a job after graduation, so they stopped him.

In the end, Liu Lu was admitted to the School of Mathematical Science and Technology of Central South University, which met his parents' expectations and persisted in his hobby. Liu Lu, who went to college, loved mathematics as always. Some students play karaoke after class, and college life is rich and colorful; Liu Lu, on the other hand, goes to the library to study various mathematical problems whenever he has time.

Sometimes staying in the library all day is not enough. He had to borrow some English math books and take them back to the dormitory to continue his research until he got the answer. Strangely, though Liu Lu was so obsessed with mathematics, he didn't get top marks in every exam.
