Last week, my friends and me went to watch Jay Chou’s performance in Guangzhou. There are crowds of cheerful fans there, many of who came from other cities. Jay began his performance with one of his most famous song. We all cheered and shouted out his name, but some even cried with joy. When Jay began to sing the seventh song it called Sunny Day, it started to rain. Therefore, the concert was not interrupted and we got even more exciting in the rain. At last, Jay finished the concert with a speech, thank his fans for always supporting him. What memorable experience!
