Liz (thora birch thora birch) was born in an American slum. She has been plagued by family problems since she was a child. Her parents drink and take drugs, and her mother suffers from schizophrenia. Poor Liz needs to go out and beg, wandering in the corner of the city, and the suffering of life seems endless. As she grew older, Liz knew that only learning could change her fate and get out of the quagmire. She won a test paper from the teacher, completed the answer beautifully and won the opportunity to study. From then on, Liz began her long journey of studying. She tried every means to apply for a full scholarship to Harvard, and she didn't even have a decent dress during the interview. However, poverty did not stop Liz from making progress. In her life, never back down's struggle is an eternal theme.
