What's the story in Zhang Yingxue's Dancing Shoes of Life?

Dark night, cold rain, empty steps dripping into bright places ... With regrets, lonely hearts, people who can't wake up ... Life is like a passing cloud, blowing in the wind. Life is like a swift river, which is gone forever. Life is a stage and a load of life. Everyone's life is to put on the shoes of life and dance on the stage of life! One day, when a dancer can't stand on the stage, what kind of test will life experience? One day, when the audience carefully measures this stage, they will find that the stage is like the blue sky and boundless. On that day, when I walked into the shoe store, I found that even if I crossed the mountain and the ocean, I would still stay on the stage of life. On that day, my heart surged, and I felt the elegance of the girl on the stage ... The shoe store was noble and elegant, with all kinds of casual sports shoes and high-heeled mini shoes ... but the most attractive thing was the ordinary pink canvas dancing shoes. I glanced at the voice of a group of people not far away. It turns out that this family is choosing shoes for their baby daughter! The girl is surrounded by her parents, so she can't see, she can only hear. Crispy and sweet, not very old. I was thinking, when suddenly came the girl's voice: "That pink dancing shoe is really beautiful!" " "Yes" or so. "But what size do I wear? "Suddenly, there was silence." It was a size 36 two years ago, but now it's about a size 37. "The girl said to ask the clerk to wrap her a pair of size 37." Don't you want to try it on? "I was thinking," I probably want to put on a big lady's shelf! " "I think I accidentally saw a wheel from the gap between people. Why are there wheels? I turned around and saw the family pushing a girl in a wheelchair towards me. I just stood there, unable to believe my eyes. The girl held those pink dancing shoes tightly and turned away from me with a smile. Later, the salesman told me that her name was Lin, and she was an elite ballet dancer of the Municipal Art Troupe. Unfortunately, she lost her feet in a car accident two years ago. From then on, she was separated from the stage forever, just like Qianshan's block. Fortunately, the girl is optimistic, which gives her a new life. Without feet, why do you need shoes? Most people might say that, but it means a lot to that girl. Without her feet, she can no longer stand on the stage of reality, but the stage of life still exists, as long as she has dreams and is positive and optimistic. You can dance wonderfully on the stage of life! A pair of pink canvas dancing shoes, a pair of dancing shoes suitable for girls' life, a stunning dance drama and a wonderful life. Every time I think of that day, my heart will be agitated. I will quietly look out the window and feel the clear water, white clouds and green grass ... I often think that with realistic and abstract pairs of dancing shoes, how can we stage a bad life dance drama, make life full of sunshine and moisten the rain and dew everywhere. Sunny day, bright sunshine, shining in the middle of the lake. Persistent dancers, firm beliefs, let dreams soar in the blue sky!
