Everyone should have a dream. What if it comes true? —MaYun

These words have encouraged lots of people to work hard. They may also tell us why Ma succeed.

    The 54-year-old man had a dream. He wanted to make a difference. He worked hard and founded Alibaba. The company changed the way people shop. It grew to be one of the world's biggest companies. It also helped Ma become one of the richest people in China.

    However, Ma wanted to do more. On September 10, he said he would retire from his company next year. He would turn to education.

    Ma is always interested in education. Before he entered the business world, he was an English teacher. He taught in a college in Hangzhou for six years.

With much money now, Ma wants to focus on charity(慈善). He creates a foundation (基金会) to make education better in rural China. His name on Sina Weibo is "a spokesman for village teachers."

    "I love teaching," Ma said. "It's something I think I can do much better than being a CEO."

    In 1834, the clock tower in London was burned down. People planned to build a new clock which would be the biggest and best in the world. So the clock had to be big and keep very good time. The big clock was made in two years. Five more years later the tower was finished. Then people put the big clock in the tower, and made it ring out for the first time on July 11, 1859.

    In order to give the big clock a good name, people held a meeting. Someone wanted to call it the Queen of Bells, and someone thought Victoria was good. At last, a man named Benjamin Hall stood up. He was a big man. Before he started to speak, someone shouted, "Why not call it Big Ben?" Everybody laughed and agreed with him.

    From then on, Big Ben became its name. And it also became a famous building of London. People all over the world write to Big Ben. They even send birthday presents-bottles of oil to help keep Big Ben running. Big Ben is not only a clock but also a dear friend of people.
