Last summer holiday, I went to Beijing with my parents. It was such a fantastic trip. First, we visited the Bird's Nest. It was huge and looked very grand. I learned some interesting stories about the 2008 Olympic Games there. Then we went to the Water Cube. Its blue, box-like appearance was so cool. We took lots of nice photos in front of it. We also went to Tian'anmen Square and tasted delicious Beijing Roast Duck. I really enjoyed my time in Beijing and I wish I could visit it again.
