Fragrant Hills Park is located in the western suburbs of Beijing, with beautiful scenery and lush greenery. As early as in the Yuan, Ming and Qing dynasties, the royal family built a palace on Fragrant Hill, which is a royal garden with mountain and forest characteristics. The temperature was moderate and the air was fresh. In this historical garden, students were very energetic, wearing disposable gloves and looking for garbage in the grass. No matter how hidden the plastic bags, drink bottles, and paper scraps were, they could not escape the eyes of our little “scavengers.” After a while, everyone’s garbage bags were filled with “treasures.” Even passing tourists in the park noticed the students’ efforts and were touched by it.
