    Last Sunday I went to the Bird's Nest Stadium, there I met some young America tourists.

    I greeted to each other and began to chat. From chat I learned that they were college students study at Beijing Language University. They all seem to love Chinese culture. As walking, they were busy taking picture of the Stadium. Apparently, we were impressed by the grand gym. But then I felt very proud that China was becoming more and more attractive for foreigners.
