An Unforgettable Trip
I took a trip to Yunnan last summer vacation. I had a wonderful time.
I went there with my parents and two cousins by plane. The weather was sunny and cool, just right for the trip. We stayed in Yunnan for seven days. We did something interesting. We visited some places of interest, such as the Wild Animal Park and the National Park. We fed the birds and rode bicycles. We also took many photos and ate delicious food. The fruits there were very fresh and nice. On the last day we went shopping and I bought some special gifts for my friends.
The trip was so wonderful that I want to visit Yunnan again.
