Yesterday I showed to my friend Peter around Beijing city. We started off at 8:00 a.m. First we went to the Forbidden City, which was one of the most popular tourist spot in Beijing. Then we visited the History Museum. We observed a lot of valuable things in them and we learned a lot about Chinese history. After a quick meal, we went to Beihai Park. Upon arrival, we were all struck by its beautiful scenes. We spent a whole afternoon appreciated the wonder. It was until 18:00 p. m. that we went back.

We did have a wonderful time. Peter was very pleased with my arrangement that he invited me to a new-built western restaurant to have a big meal.
