Everyone has his own strengths. In my long memory, there are many people I admire. There are city beauticians, cleaners and aunts; A teacher known as a hard gardener; A tenacious uncle in his career. Among them, I admire my classmate Xu Moumou the most. Because her spirit of studying hard deeply touched me.

Once, the math teacher came up with a problem that no one had ever seen before, so almost only one percent of the people could work it out, and Xu was no exception. Ding, after class, my classmates and I flew to the playground, while Xu sat in his seat, thinking hard.

After school, I went to see Xu with my new racket. Just entering the door, a burning smell came to my face. I turned my head to look at Xu Moumou and found that she was sitting on a small bench, writing and painting intently. I went over to bring the rice down and said to her, "The rice is burnt." She reacted as flustered as last time, smiled apologetically at me and said, "What can I do for you?" I shook the ball in my hand and said, "Let's play badminton." She took out a pen and paper and said to me, "Let's stop playing and study this math problem."

I asked a few questions and finally figured it out. We both said in unison, "It's solved." Before you know it, it's six o'clock, and the "tick-tock" bell rings, as if to celebrate that we have solved this problem. The street lamp by the roadside lit up the street, so I quickly picked up my racket and rushed home.

Whenever I think of Xu Moumou, I will give her a thumbs-up because she told me to study hard and persevere.
