Early in the morning, having assembled outside the school gate, we head straight to the destination. We set out for the top in high spirits when the moment we arrived at the foot of the mountain.

Laughing and cheering, we eventually reached the summit, which we enjoyed the bright sunshine and cheering, we eventually reached the summit, which we enjoyed the bright sunshine and fresh air. Viewing from the top, the city was beautiful. Bathed in the warm sunshine, we entertained us with stories, songs, dance and games.

Therefore, we strongly suggest that similar events are held every year!
