From the eighth place in the preliminary contest to the third place in the semi-final and then to the second place in the final, leg pain became the mark of the struggle of the students. The evening's Yifu playground witnessed the efforts of the students of Class 1809. Every practice of changing jumping is a reflection of the students' constant transcendence and unity. The whole process was hard, but there was love. Cheer up and insist. The best of Class 9 became the best memory of training and competition. Through this long rope competition, the sports spirit of the students was promoted, and the good style of unity and progress of Class 1809 was demonstrated. We hope that Class 9 can achieve better results in the next class collective activity.
