One Possible Version
Last weekend, my classmates and I went to Mount Juci. It was so interesting.
It was a sunny Sunday. At 8:00 in the morning we met at the school gate. When everyone arrived, we started. All of us like riding, so we went there by bike. After about 80 minutes’ ride, we got there. We found it a beautiful place because there were many flowers and fruits there. So some students took photos, some played games or picked flowers. The others sang songs. At half past three in the afternoon, we got back to school. We were tired and hungry but we all felt very happy.
