Chairman Mao once said: “It is not hard to do one good deed. It is hard to do good deeds all your life.” Guo Mingyi, 52, a worker in Anshan, Liaoning, did just that. Over the past 20 years, Guo has donated 60,000 milliliters(毫升) of blood. That is the blood of 10 people put together.
   Once, on a cold winter of 2009, Guo got a call from the hospital. The doctors told him that a patient needed a blood donation. Guo didn’t have time to eat lunch. He travelled in the snow to get to the hospital. When he finished donating the blood, he was so tired that he fell asleep on the hospital bed.
   Guo and his family live a simple life. He and his wife and daughter live in a house of only 40 square meters. They don’t have a lot of money, but Guo saves money to support poor children. In the past 16 years, he has donated over 100,000 yuan to more than 180 poor students. When the parents met him, many cried. “He looks poorer than us,” they said.
   Guo has also offered hands to thousands of workers, friends and strangers. His warm heart has moved many people. They call him a “Modern-Day Lei Feng”.
   Recently, Chinese leaders called on people to learn from Guo. They say young people especially should learn his selfless devotion(无私奉献).But Guo said he did these things in order not to get famous. “It’s just that some people need some help, and there should be someone standing out to give them a hand,” he said.
