Last week, I, along with the rest of my grade, went on a 18-hour survival training trip. When we arrived in, we put up our tents before making lunch. Then we participated in team-building activity such as dragon boat racing or rock climbing. They were all extremely fun yet tiring. The most excited event was the boat racing, as I have never been in a dragon boat before. The thrilling feeling of riding over the waves will stay my mind forever. By the end of the day, they were all sweaty and exhausted. We packed up the next morning, take back with us our new created memories.
