Life is full of various experiences, some of whom are unforgettable. I still remember the hiking experiences with my classmates for 16 kilometers to Hailongtun two years later. That summer day, we set off early in the morning, think it would be great fun to walk for so long a distance. However, with the weather is getting hotter and hotter, I found their legs heavier and heavier. What’s worse, my feet began bleeding because long time pressing against the shoes. At one point, I even wanted to give up. And I managed to drag the rest of the way to the destination. Though not pleasant, this journey was impressive and rewarding. I have learnt that life is the long journey like this. No matter what happened, we should never give up.
