Last weekend I went to the Great Wall with my colleagues, and this was my first time to visit it even though I grew up in Beijing. The Great Wall has many sections, the one we visited was the SiMaTai section. We went there about two weeks late, the leaves almost fallen off. And there have many stray cats, a little cat even accompanied us as we climbed up. What a pity we didn’t have any food for her. It's really been a long time since I last exercised. Even though we took a cable car and only climbed a part of the wall, and not reached the top. I still felt exhausted. Today, the muscles in my arms and legs are really sore.🤣
