Lei Feng was a man who lived in China a long time ago. He was famous because he helped people a lot.
When he was alive, he would do nice things for people, like help them carry heavy things and fix their bikes. He also volunteered to help clean up the streets and he donated his own clothes to people who needed them.
Lots of people in China heard about Lei Feng and they thought he was a really great guy. They even made up stories about the kind things he did, and some people started to believe that he was a superhero!
