Who has done something that shocked the world in a short period of time?

Jack Ma, the founder of Alibaba in 1999, never gave up on his dreams. He once wanted to get into a key elementary school, but failed; he also failed in a key middle school; it took him three years to get into college; he wanted to get into Harvard University, but he didn't succeed either. But he had the spirit of perseverance and courage. As the saying goes: "The edge of a sword comes from sharpening, and the fragrance of plum blossoms comes from bitter cold." Through his own efforts, he finally succeeded. He said: Dreams must be down-to-earth and are closely related to tears.
