After God made many healthy children, maybe tired, he made poor Helen & middot; Keller. Helen, a serious illness is over, she has only 19 months of light and voice, her fate is tragic, can only live in the dark every day. But she never complains about God's unfairness and still faces life with an optimistic smile. In her opinion, suffering is the best touchstone, a kind of self-improvement and self-discipline.

These things seem easy, but for a long time, how monotonous and boring! Helen has so much to learn. She still has the patience to learn.

Helen can fight for her ideal. With such a healthy body and excellent study conditions, why should we give up? "
