In order to encourage the students to take outdoor exercise, our school organized a mountain-climbing activity on April 25. Hundreds of us took part in it.
It was a nice day. At 8:00 am, we gathered at the foot of Songfeng Mountain and set out for the top in high spirits. All the way we were chatting, singing and laughing, enjoying the fresh air and the beautiful scenery. When some fell behind, others would come and offer help. About 2 hours later, we all reached the top. Bathed in the sunshine, we jumped and cheered with joy, after which we had a wonderful picnic there.
This activity benefited us a lot. Not only did we get close to nature and relax ourselves from heavy school work, but also we developed a close friendship with each other. What a memorable time!
