A movie, in which the heroine plays a model, became famous later. What's its name?

Don is an ordinary girl. She also knows that she is plain and average in figure. She comes from a small city in the south, a single-parent family and goes to an ordinary college. Her employment prospects are not optimistic. But Tang has a firm belief that she will stay in Beijing, take root and bring her mother to Beijing. After graduating from school, Tang had little savings left. She found a cheap house to share with others, but her roommate turned out to be a boy-Yan Jie. Tang's careless personality makes some cleanliness a headache. Their common life was not smooth at first, even full of hostility. Although life is not satisfactory, Tang found a job as a shopping guide with the help of her friend Lele, which temporarily solved her economic problems. Tang is optimistic by nature. Even as a humble shopping guide, she is conscientious and often helps customers try on shoes. Although Tang has a good figure, she has incredibly beautiful feet and eye-catching shoes. Soon, her enthusiasm and beautiful feet attracted the attention of a strange old man. The strange old man gave Don a business card. He used to be the boss of a special model economic company. Don became a model for no reason. The strange old man has high hopes for Tang, thinking that she will lead the company out of trouble. The departure of Kym, the former star of the company, has brought a great blow to the company. The job of modeling is not as simple as Don thought. Although she has excellent innate conditions, to become an excellent model, she still needs training and efforts in all aspects. Tang's coach Wang Wei is a famous devil coach in the whole company and even in the whole circle. In order to catch the grand press conference at the end of the year, Wei Wang began to train Tang in hell. Want to become a model, not only need hard training, in this respect, Wang Wei has never given Tang a good face, and is very strict with her. In addition to training, a series of harsh foot maintenance methods have also become Tang's nightmare. Mother's incomprehension and opposition also made it difficult for Tang to persist. Perhaps the only comfort for her is that Yan Jie seems to have changed something for her. The hostile relationship between them eased from the beginning, and Yan Jie encouraged her to try her best to follow her own path. Don insisted, for the secret of her heart and her childhood wish. In this process, Tang realized that every girl is extraordinary. They have their own unique beauty, but they need to explore and show this beauty through their own efforts. In fact, every girl is a beautiful angel, and each of us has our own bright spots. We just need to find a beautiful self from another angle.
