Yesterday I showed to my friend Peter around Beijing city．We started off at8：00 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.
