Write a composition on the topic of being strong. The smiling little girl wrote a 500-word composition by Zuo Zuo.

Unforgettable smile The rain suddenly began to rain. I had to hide in a humble newsstand. Some people have come to shelter from the rain. They used the newsstand to kill time. Among them, a woman shuttled through it. She carefully arranged newspapers and magazines. For every customer, she will introduce every publication with a smile. Her smile is sweet, just like a ray of sunshine after rain, giving people light and warmth. Perhaps it was her smile that touched people who took shelter from the rain. Many people are willing to pay for some books here. Perhaps it was her introduction that made people easy to understand and found their own "treasure" in this sea of books. It was still stormy outside, but her smile was not washed away by the storm. More and more people came in to take shelter from the rain, as if because of her smile, which made this originally humble newsstand clearer and full of vitality under the erosion of wind and rain. The surrounding atmosphere seems to be activated at this moment. Looking at her smile from a distance, I seem to see the contempt for the predicament and the tenacity in the predicament. A faint smile can make people feel fearless in the face of wind and rain, calm in the face of difficulties and firm in the face of difficulties. When I walked out of the newsstand and looked back at it again, the street lamp shone on it, and the rain wet its "coat", which seemed to show a joy of overcoming the wind and rain. It stood there, smiling at the people coming and going in the street, as if waiting for the next challenge. An ordinary smile has witnessed many hardships. Facing difficulties with a smile, it will be full of warmth, meet the challenges in life with a smile, and let us go on with confidence. If a smile is a ray of warm sunshine, it makes life colorful; If a smile is a tender green grass, then it gives life to the earth; If a smile is a brilliant flower, it makes the world no longer lonely. It was that smile that gave me infinite strength and made me learn to be strong. That smile, a smile after two years, is still deep in my memory and can't be erased for a long time. It was a day in May 2008. I followed the Wenchuan earthquake on the Internet. My eyes couldn't believe it when my finger rolled on the mouse. Bloody, cruel and painful scenes. The building collapsed, crushing the people below alive, and the animals scattered. It was dark, and some people who had just escaped from the clutches of death were hit by reinforced concrete on the building ... really, it was terrible, terrible. I continued to scroll down, when a lovely little girl caught my attention. She is not like those bitter photos. She, in the ruins, was covered with blood and her clothes were covered with dust. Her hair is messy, but she has a smile, and that sweet smile sets her off very cute. I read the following words. She is a ballerina. She likes dancing very much. In the earthquake, she had to choose amputation. I rubbed my eyes. Leg amputation? It is very painful for an ordinary girl, not to mention that she loves dancing. Not only that, she lost her parents in the earthquake. "My God!" I really can't believe she smiled so brightly after all the pain. I began to admire her and pay attention to her. The second time I saw her, it was in the newspaper. She is still smiling, but there is no blood on her face, her hair is clean and tidy, and the background is the ward. I read the article about her carefully. She is only seven years old, but she said, "Now that it's over, laugh. Difficulties are spent with a smile. I love to laugh because it won't hurt me anymore. " That smile, sweet smile, may be the most beautiful smile in the world? In the days to come, I will learn from her and laugh at difficulties.
