Life is full of various experiences, some of them are unforgettable. I still remember the hiking experiences with my classmates for 16 km a year 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. But I managed to drag the rest of the way to the destination. Though not pleased, this journey was impressive or rewarding, I have learnt that life is a long journey like this. No matter what happened, we should never give up.
