In view of this knowledge, my parents and I arrived in Beijing by train in a summer vacation. After arriving in Beijing, we went to a friend's house of my mother and settled down. After settling down, we drove to Badaling Great Wall. After arriving at the station, we entered the gate of the Great Wall, and two roads came into my eyes. We picked a road at random and began to "stroll" on the Great Wall. Just a few steps later, my mouth made a sound of "ah" and "ouch". It turns out that the road here is sometimes slippery and sometimes steep, so I fall to the ground from time to time. In this long city, I saw many people's autographs, such as "Chen Jie has been here" and "This treasure has been here from afar". Here I want to appeal to everyone: we should protect the natural heritage. I also found many traces of being attacked by gunfire on the Great Wall.
