My name is Wei Yanyan. I don't know which day, everyone called me "Little Mariko". The face is long and round, and over time, I find this nickname quite interesting.

When I run, I change my feet quickly and take small steps. I run step by step. Every time I run, my classmates laugh at me: "Xiaoyu, your running is really interesting, like a ball rolling very fast." Ah, really? I haven't seen it, but I know I run fast, especially in sprints. At the sports meeting, I actually "rolled out" some famous things, twice in the 4 * 100m relay with three other people and twice in the 100m relay. I am proud to win honor for the team.
