I Was Sweeping Floors at Tsinghua and Peking University When I Solved the World's Math Problem

Yang Keqin, a top mathematics professor in Longguo, wants to test the abilities of the latest class of doctoral students in the mathematics department.

He gives them the world's most difficult equation: an advanced Fourier equation that only a handful of mathematical geniuses anywhere in the world can solve.

After setting the problem, Professor Yang doesn't actually expect any of the doctoral students to solve it.

But to his surprise, the next day, eight different solutions have appeared on the blackboard, and all eight are correct.

Professor Yang is stunned and wants to know which doctoral student solved it, but when he asks, nobody admits to it.

In the end, Professor Yang discovers that the person who solved the advanced Fourier equation is a young janitor at Qingbei University with only a junior high school education!!!
