    A week in the sun relaxing in the beautiful March weather of Varadero, Cuba is a fantastic place for anyone. Luckily, my wife, two friends and I had the chance last year.

    To see Cuba, you have to talk to the Cubans .Our friends met us at the airport even at 1：00 a. m. which started our trip on a positive note .After a few days at the hotel, we got to know a local guide, Victor. The trip started off on a sunny morning. Our return trip would be along the coastline from Havana, but our trip to Havana would be through the countryside and the small towns. This trip was designed for us to visit the Cuban countryside. At first Victor brought us to Revolutionary Square, where Fidel Castro made his yearly speech praising the ideas of the revolution.

    Our second stop was the Bocoy Rum Factory. We walked through and learned how 5, 000 bottles of rum(朗姆酒)are produced every day. The smell of rum, and the huge barrels were interesting.

    The final stop was the market in Old Havana. Here my wife and I went away from our friends and we toured through this large shopping center. From store to store we saw so many items that all had a clear Cuban feel to them. We bought a picture and some special local things, and then we took off to meet up with Victor. As a tourist I was able to have a quick look at Cuban life with the help of Cubans .I felt lucky to have the chance. It was an interesting experience in my life.

    On Sept, 19,2014 Alibaba went public on the New York Stock Exchange (纽约证券交易所), raising $25 billion through an IPO (公司股票的首次公开发行), the biggest in the US history. It shows that Ma Yun has done his business successfully. The short Chinese man seems to be the tallest in the world right now. Ma, who was an English teacher, has become one of the richest men on the Chinese mainland.

    Born in Hangzhou, Zhejiang, Ma grew up as a happy kid. At the age of 12, he wanted to learn English. Every morning, he woke up at 5 a. m., cycling 40 minutes to a hotel near the West Lake where he could chat with foreign tourists.

    On a trip to the US in 1995, Ma was shown the Internet for the first time. Seeing the chance, Ma returned to China and set up a website called China Pages without even knowing much about computers.

    Four years later, 18 people including Ma, his wife and his friends founded Alibaba in Hangzhou. People called him "Crazy Jack Ma". But 15 years later, Alibaba has developed into the world's largest e-commerce (电子商务) company.

    No one thinks he's mad now. Ma's favorite line has been printed on Alibaba's souvenir T-shirts. It reads, "Everybody should have a dream. What if that dream comes true?"
