During the summer vacation, my parents and
I went to Beijing for a trip. On the first day, we visited the Palace Museum
and took many pictures at there. On the second day, we went to climb the Great
Wall. It is one of the greatest wonder in the world. We saw lots of tourists
and learned much information about it under the help of the tour guide, Miss
Yang. At last we went shopping in the city centre of Beijing Wangfujing Street.
We bought a lot gifts for our friends.
We enjoyed our trip very much. It was an
excited experience and I will never forget it.
