In our daily life, we always come to the question “What is the real beauty?” . Different people have different ideas. Last night, I read a true story from the newspaper. It's about a poor, ordinary looking old woman. She lived alone, making a living by picking things from rubbish heaps (垃圾堆). However, she took in more than ten homeless children and tried to bring them up .Every day she worked from 6:00 a.m. to 8:00 p.m. In order to earn as much money as possible to raise the children and to keep them in school, she even went to a local hospital to sell her blood(血) once a month. She got so weak because of the loss of blood that she sometimes felt sick on her way home. When asked why she chose to take care of so many children, she smiled and answered,“Oh, I love children and I like to live together with them because they always bring me great happiness.” Though the old woman was poor, she was full of love and rich in spirit.So the local government and people in her city truly respected her. Maybe you can't help thinking,“What makes that poor woman so different?” It is nothing else but her inner (内部的) beauty, her true devotion of love without any thought of money. So the real beauty is the beauty in one's heart, that is, the inner beauty!
