In the 20th century, a unique individual with her brave manner shocked the world. She was Helen Keller - a woman who lived in darkness but brought light to humanity. A frail woman who lived for 88 years, and endured 87 years of a lonely life without light, sound or speech. However, it was precisely this person, secluded in a world of blindness and deafness, who graduated from Harvard University's Radcliffe College. With all her might, she traveled everywhere, setting up charity institutions one after another to bring benefits to the disabled. She was elected as one of the ten great heroes and idols in America in the 20th century by the American magazine "Time".
